I'm gonna be 28 in a few months, but I know where you're coming from. My next car will be a G35 or something a little more of a mature car. But personally I think you're never too old to mod any car. Its like the 50-60 year olds that drive around in older classic American muscle. Now that some Japanese cars are considered classics, we'll see import cars being modified more often by an older crowd in the future.
