Trying to get some ideas from the experts here on how to value aftermarket equipment on a 2006 997S.

It's relatively easy to find the value of a used stock car (even with factory equipment) via KBB, Edmunds, NADA, etc. However, what if said car came with extras such as a full Techart body kit, HRE wheels, H&R springs, exhaust, flash, etc. I read where one reader put the value on such equipment on a 2006 at 15% of the retail price when the part was new. Seriously? Only 15%?

Anyhow, just asking as I'm trying to get some ideas on pricing of some cars I'm looking at that come with the extra's and the owners point out that their cars have $10k, $15k, etc. of aftermarket equipment.

Thanks for the help/advice/opinions.

 

A general rule of thumb I use is that parts are worth roughly 50% of their value. That is more true when the parts of taken off the car and sold. If they are installed they may actually subtract value if the buyer perceives them as doing so. 15% is probably a resonable number if you actual want the parts. Heck, buy them at 15% and sell than at ~50% if you don't like them.

 

I agree with above but I'll be more direct about it. Your best bet to sell the car is to sell it as it came from the factory. Holding out for that buyer who wants your aftermarket stuff can be time consuming and severely decreases your buyer pool.

That said I agree with above, 50% for used aftermarket stuff is fair, some parts can demand more, but any wear item (dampers, brakes, short-shifter, etc.) figure 50%. Unique non-wear items (GT3 cloth seats say, or a roll-bar inside) can likely carry more value then 50%.

 

Unless the car is set up the way you want it, the extras are really on worth what they are worth to you! If the car has aftermarket stereo equipment and it isn't something you would have added, then it really would add much value. If you are looking at one with nice wheels, that you would likely add at a later date, then you would add some extra value to the car. The end of the day, $15K in extras will never add $15K to the value, they will depreciate as fast or faster then the rest of the car.

 

If you are trading in a car, the value of aftermarket enhancements is probably zero. For a private sale, it will be highly variable. Fifty percent is unrealistically optimistic. If the buyer does not want the modification, it is valueless or can kill the sale. A good rule of thumb is probably ten percent.

Practically speaking, if you don't plan to keep the car long term, only order the vital options (heated seats and the like) and don't spend significant money on modifications. Expecting anything over routine list price, including reductions for mileage, reduced value for accident repairs and perceived or real hard use of the car is unrealistic.

 

If mods are easily removed, such as wheels, I don't mind paying a little for them knowing I can remove them and sell them (for no more than 50% of new cost). Most of the mods I installed on my car can be removed before I sell the car and re-sold, unless a buyer specifically wants to pay the same price for them left on the car.

A mod that the buyer doesn't want is worth nothing to him unless he can remove and re-sell it easily.

 

If the car is modded you might actually get less than blue book as a modded car sometimes suggests a hard or abused life. The value of the mods is probably worth at the max 15% of original price and that is only if the parts are quality and you have receipts of their professional installation. If not then, other than wheels, you probably wont get any money back on your mods and the car might actually have a lower "market" value. If you can remove the mods and sell seperately, I would suggest you dot that. In this case they can be sold for about half of the original price.

I believe that the BUYER determines the value of any mods, just as he pretty much determines the value of any factory options. A person looking for a performance sportscar isn't going to care much or pay anythng for PSE or Techart or a fancy interior or a 6 disc player, but might be happy to pay 50% of the 'new cost' for hp enhancements or a better suspension. Conversely, of course, the buyer looking for a 'statement' car might be happy to "steal" the same Techart, or BBS Rims, or full leather with deviated stitching, etc. at half price. So, Joe, I wish you good luck in your search - use the conventional (such as Edmunds) pricing guidelines and then decide how much more, if any, the full Fabspeed exhaust with flash or the Makassar interior is worth to you.

(not enough yet. almost soon...here is your answer)

Here is the best answer I can give you to your question you PM me about. What it really comes down to is what would be your plan for the car?

I all along was planning on lowering the car, putting a body kit on. The exhaust and intake were bonus mods that I would not have necessarily cared about. So for me, the cost to put on the techart kit would have been $3100 for the rear wing, $2400 for the sides and lip, plus install and paint work. This would mean at least another $500-$700. So the kit on the car I just got would have cost me about $6k, give or take. After seeing the car and the car being in MINT condition and this stuff JUST added, to say now that the cost is only worth 15% of what they put into it, does not add up, because I feel the car has added value because this is already done. The same with the suspension. Your looking at $340 for the springs and another $600+ for the install and alignment. Again, with it being already done and ready to go, less time without the car and already taken care of for me. Again, this ADDS value to the car in my case. The bonus becomes the intake (which costs $600 new) and the exhaust that is on the car (which would have cost $2k new), again bonuses. Based on the FMV of the car, with the options it came with (in my case) and without the mods, the car should have sold for about $56-57k, given it only had 8k miles. With the mods, they were asking $62k. Regardless of what I paid for the car, just doing the math on the body kit alone and the car is WORTH $62k, even if ultimately I did not pay that. Hope that makes sense. I think if you are looking at a similarly spec car, then anywhere from $58k-$63k would be about right, plus ttt. Now if it also come with a nice set of wheels, that may add another couple of thousand to the deal.

skizot,

Thanks for the great and thorough reply. What you say makes a lot of sense. The car is MINT so that really helps. I like (not love and not sure I would have done the add on's myself) some of the aftermarket items. Others I don't care so much about. Actually, what I am finding out that may kill the deal for me is the ECU Flash. I'm finding out more and more that many dealers will void the warranty (car still has over a year of warranty left) if they find out you have ever installed an ECU Flash in the car. Oh well, maybe if I have so many doubts about this car it's best that I keep looking. As others have said here, there's many, many cars out there for sale right now and is definitely a buyers market.

 

I spoke with my dealership today (see other post just made about Porsche of Orlando) and they have been great. Very informative and honest. They said, it does not necessarily void the warranty, BUT they would typically partner with an adjuster and that is where PCNA comes along and says, no no no. So I agree, if it is still under warranty and that is important, no ECU flash. I am glad my car does not have this.
