I understand the first post, because I've felt the same way. That is why I havent spent any money on my car that I regret. All my mods have had a tasteful, functional nature. If my tastes had changed, I made sure I was able to sell it at least 80% of the price i paid for the part, which also was almost always pre-owned to begin with.

I just know that my next car will be good from the factory (most likely Sti), so modifications, if any, will be limited to good wheels/tires and minor suspension work.
