what made me laugh this weekend was i was in erballs car thinking wow, this car is so quiet. then i hear him talking about how the smf is so loud and the engagement is rough. that solidified in my head that different strokes are for different folks and i'll just stop telling people that the smf is worth it. i guess i just have a different tolerance for that kind of thing, especially since i'm the only one in my car 99% of the time so other's opinions don't effect my purchases. but the best bet is to sit in a car with it and make your decision then.
