It's probably up there, or at least in the 16-35 age range any way...I guess it depends on what you want to do to your car...and if you're already worried about resale....well.....one word....issues.....hahahaha...jk.

As far as resale goes, realistically, you can put basically anything back to stock, and recoup at least some of the money you put into mods. For example, a Jackson charger, will sell on ebay for anywhere from a 1-2K used depending on condition, and other than a couple minor bolt ons, your car can be back to stock in an afternoon. As far as resale goes, though in some cases a stock car will fetch more money...If you're willing to be patient, there are those people who with the correct mods are often very interested in modded cars....As far as going into the bottom end, if you plan on selling it soon, it's not worth the money any way...if you're keeping it, who cares about resale...I think your enjoyment is far more important...worry about resale when that time comes...just keep all the parts handy....

Later,
