I’ve never really had the heart to tell those young whippersnappers on Yahoo! Answers that there might possibly be better ways to spend their hard-earned cash than trying to squeeze an extra 10 hp out of [car deemed inadequately speedy]. Perhaps it’s because I lack this level of eloquence:
When you modify your car, what you’re doing is trying to resolve a deep insecurity. This is what’s wrong with modifying your VW: what issue are you exactly resolving? Safety? Reliability? Lowering your cost of ownership? My answer: you’re just bored with your ride. If you acknowledge that to be the case, you now recognize that you’re living a boring K-selection lifestyle and now is your chance to move towards an r-selection lifestyle in the fast lane.
So start modding that car. Because cars are often the only thing that has meaning to a young guy. Then, when you’re looking at settling down in 10-15 years, feel free to discard it all and start over again. Meanwhile all those boring people you dusted with your hot car have done things like travel, paid off debt, or upgraded their skills so they can write their own ticket in a down economy.
That’s gonna leave a skid mark.
