Why Modifications Don't Make Your Car More Valuable

    the way I actually made money on modifications on a car I used to own was by installing upgraded original parts. I installed the factory sports suspension and did some minor tweaks to the engine so it ran exactly like the higher eingine choice. cars with that engine and that suspension goes for more than it cost to get the same parts from the scrap yard. so I bought that car for $600, spent another $600 and sold it for $2000. but I put more hours on it than the extra money was worth and I would have made more money just to work the same amount of hours at my job.
    it was fun to do tho and the car was really fun to drive for a while so I still think it was worth it

    This is amplified when we start talking about pick-up trucks. At least 50% of the buyers will be looking for something to use for work. Once the suspension has been messed with it becomes useless as a work truck. Add the gimmicky tail lights, wheels, grill, shaved tailgate handle, and etc. it becomes worthless to anyone other than a teenager. One thing I'm surprised you didn't touch on is the quality of the mods. For the most part it's a guessing game. Especially engine upgrades. There are so many little subsequent upgrades or adjustments that need to also be made. Did the mechanic really know what he was doing? Many of those mods become a liability and a risk. I'm not paying more for that.

    As an unapologetic automotive purist thank you for making this video. I will admit I will give an exception for commercial/work purposes or for daily non- classics if it increases the usability or enjoyment with the understanding that vehicle will likely never be more than a loyal daily driver. For example I put an aftermarket head unit in my 03 Yukon. I also went to 17 in GMC wheels rather than keeping the stock 16 in because here in Oklahoma 17 in tires are much easier to find and actually costs less. Now as far as classics go. I like seeing carburetors, inline 6 cylinders, drum brakes etc etc. I do understand the safety and reliability concerns and if a classic is seeing lots of miles I can understand that viewpoint even though it always rips a part of my heart out when I see the old technology being lost.

    This applies to houses sometimes... sometimes, like modifying a room or house to your taste very specifically, a good example on the really high end is Michael Jordans mansion that was on the market forever, this can happen on a smaller scale though, like installing a low quality above ground pool or like a pokemon tiled bathroom or something weird.

    Why people expect to recoup the retail cost of their mods is a mystery. If the car has depreciated say, 40% from new then so have the mods, if not more. Plus many modifications just replaced a version of a thing the car already had. Nothing was really added to the car just replaced.

    I inherited a '73 Buick Limited [Electra] my dad bought brand-new. I'm even hesitant to upgrade the radio because I want her to be JUST as she came from the factory. No wild wheels and tires or exhaust mods either. Triple black 2-door, the paint isn't the greatest but I won't repaint because then she's no longer original! I've turned down ridiculous amounts for her BECAUSE I keep her all original. It's true; they're only original ONCE.

    The title of the video should be renamed as “why modifications don’t add value to your car that’s gonna be sold to the market”

  • TheMoneylender

    I feel like Doug missed the biggest point. The main reason why YOUR mods don’t make your car more valuable is because YOU lack credibility
    If you think about it, an m3 is just a modified version of 3 series, AMG is just modified version of a mercedes, however, they are significantly more desirable because it’s done by credible people.
    When YOU make modification to YOUR vehicle, it could be significantly better than the stock version, but to others there is always that uncertainty whether it’s been done properly. Did they use ductape? Are all the bolts properly torqued? How is this going to affect other components? Did this person take any shortcuts that they shouldn’t have? What do they actually know about engineering? Etc..
    This is why cars tuned by established tuning companies, or high performance division of manufacturers, are significantly more valuable than their stock counter parts. Ie, Alpina BMW, RUF porsche, Blackseries mercedes, Callaway Corvette etc..
    Mods that improve driving experience, wether that is more power, less weight, better brakes etc are more desirable, but not at the expense of safety and reliability. So when YOU install quad turbos in your garage, people are gonna wonder if overall package is going to work.

    Good stuff. I was an insurance appraiser, and thankfully I rarely ran into someone who was aggressive about how much their car was worth with mods. Granted I was on the repair side of things rather than the selling side, though sometimes people were also planning to get rid of the car anyway so value did come up. Basically everyone I talked to about was realistic about how the money they'd put into the car was pretty much gone.
    I think the most anyone had ever put into a now-totaled car was like $3k, about twice what that car was honestly worth, but that guy was well aware he had been essentially throwing his money away too. Around here what most people spend the big money on is oversized wheels, and that market is substantial enough that it's not a bad investment.

    I couldn’t agree more! You were 100% SPOT ON in this one Doug! I’ve been looking for a used Diesel Truck for a couple months now. And even though I plan on tuning it, doing exhaust, intake and all sorts of other mods. I DO NOT want YOUR mods. Even if some of them are what I would have picked myself. Part of the value in mods, in my opinion, is doing the mods yourself! Or at least the before and after reaction you have in your own head when modding something.
    For example… it’s fun to drive a tuned compound turbo diesel truck for a test drive. But I think it’s even more fun if you experience the original power level and then get to experience the massive increase in power after modding.

    "Let me buy this 1930-40s era stock, complete car and add the 50k in parts and labor to make it go and stop like modern traffic, instead of buying a street rod already done for 40-50k" Yeah -- buyers don't think that way. I will say the points argued in this video do generally kick in collector cars built later.

    I worked at a dealership in college, it was exceptionally true of GMC Yukon and Denali's with huge rims, we would ask if they still had the original rims and if the answer was no we would drop the trade-in offer by 4k instantly. Because no one would buy one of those trucks used with weird rims.

    I understand your argument regarding especially showoff kind of modifications. However, this seems to apply to manufacturer options also, to a certain degree, as not everyone will want additional screens, a sunroof and so on. That said, to the person who modified this video... sorry buddy but we will not be needing your services from this point in time onwards.

    C6Z. Heads/cam/intake cars CONSISTENTLY sell for significantly more money than stock/near-stock cars with similar miles/condition.
    One of the big reasons is the valve guide issues with these cars - many buyers want this addressed, which is addressed when doing the heads. Will get your parts cost back out in resale? Typically no (well, if you did them a year ago, absolutely in today's crazy market). But you will get several grand more for the car than one without that done.
    I got lucky with mine, and only paid a couple grand more for mine already modded than if I had bought a stock one, but I bought well and can sell for well over what I have into the car.

    Shitty or limited mods don't improve value, but a well-built beast of a car built on an inexpensive chassis can greatly improve the value of the inexpensive chassis. Let's use a 1000 hp 2JZ in a 350z with track-worthy supporting mods as an example. You'll never recover your money, but the $5000 chassis can be, and are commonly sold for $25000.

    I've modded cars before and sold them and I very much agree with this video. You would be delusional to think you can get every dollar back of the mods, sometimes it will increase the value it's only about 50% of what you paid for the mod not including installation. I recently sold my off road truck which I considered modded the correct way and actually got full asking price from the 1st person intrested $3k over Kelley Blue Book. That is one example of a sale going the sellers way but often it does not happen like that. GREAT VIDEO DOUG

    I bought a super clean NA Miata about ten years ago for $3600. It had hard top and was bone stock. I put in easily over $10k in "tasteful" mods, really nice paint, wheels etc. I ended up selling it for $7500 about a year ago. Didn't make my money back by any means, but it was on the market for a long time waiting for the "right" buyer.

    My first venture into modifying a car, I modded a 94 civic. Ya generic I know. I bought the car for $800 with a blown head gasket which cost $2000 to repair. Spent $1000ish on suspension upgrades, $350ish to convert rear brakes from drum to disk, and spent about $600 on repairing body damage caused by the previous owner. Among other mods, I wanted an autocross/track car that was still street legal...barely. had the car for 7 years and sold it for $1000. My original asking price was $1200. Last I heard a few months ago, it's still on the road in California where I sold it now smog exempt.
    I want one again but every one I find is swapped and/or turbo'd and they want 5k for it and it's in terrible shape. Like seriously? I'd see that if it was a B16B or K20. But you put a H22 in it. Yay. Good for you.

    if a guy who knows what he is doing modifies a car extensively, and then puts it up for sale.......these guys are into what they have done and they will show you and explain to you the nature and the extent of the modifications. if the car shows extensive mods and the seller is not presenting himself as the person who commissioned/did the mods or knows much about it- back off. believe it or not these guys may have vastly improved the car or maybe not- as a car-buying person you need to know the differences so you can decide if the car is a good value. maybe the guy built a motor for the car using older and possibly quite rare parts which may or may not be OE stuff. maybe the cylinder head, valve train, and crankshaft/bottom end stuff is unavailable now or terribly expensive and hard to find. maybe the car has a rare transmission or a very expensive final drive unit. you have to know what you are looking at and decide if you will be able to duplicate it at a reasonable cost- a given engine and drivetrain can cost 10k or more and you can add that to whatever cost or time is involved in hunting down the needed parts. on many older cars that have been extensively modified, you really cannot duplicate a given mod if you can't find the parts (at a reasonable cost). bottom line- if you are a car guy you will know if a car is a good value. if you are not, better stick with what the factory used on that car. of course there are people will know some stuff about cars- err on the side of caution. a successful dealer parts manger (hey glenn) once said "the farther you get from stock- the more problems you're gonna have". very true, but solving problems is something a real car guy is good at and he may be willing to make a trade-off or overcome problems on his own. if you are that car guy- I salute you because i know there are so many ways to screw up the building of a street car. i used to build datsun 510s but the donor cars are just too rare/expensive now, and so are some of the more desirable used parts that are needed. too bad- it was so much fun.

    As well as the points made regarding mod devaluing the car, for me, I assume they were done by the car owner/seller, so I assume that it may have been poorly executed. Mainly with mechanical things. I don't wanna pay a premium for a car that some amateur mechanic has tinkered and messed with. Plus, even if you liked some of the mods, as Doug said it's unlikely you'll like them all. Some are easy fixes like wheels, but some may be more permanent if they'd hacked bits off of the car.
