I agree with Ducman, suspension and some super supportive seats are as much fun as engine mods. Maybe I'm just super stoked that my other seat should be coming tomorrow after being backordered for 2 months!
Don't be jealous of other folks cars. The thing is that we seldom see the amount of effort and money that it requires to have a spectatcular vehicle. I've long ago given up on having the nicest car. My car is now devoid of interior, it rattles and vibrates over every bump, smells funny and has numerous quirks. However, its decently quick, gets great gas mileage for what's been done and how its driven, and has so far proven to be extremely reliable and low-maintence (knock on wood). I haven't posted pictures of it for several months, because its not much of a looker, and its owner has a lousy eye for photography...however, the fact that no one has seen recent pictures of it on the internet doesn't matter to me when I plop in behind the wheel.
