I love loud, powerful, etc cars; but, I'm more of a "sleeper" person myself. I prefer less of a needless noise in life. I'd prefer for a powerful car to be dead to near silent as possible. weird, amIrite?
EDIT: as Mattbob said it "I prefer dead silent until the hammer is dropped. Then I want all hell to break loose. Dynamic exhaust FTW." THISSSS!
