hmmm you guys all have bad things to say. i guess we all but we cant complain for the price we are buying these cars they have turned out to be the s***! i love my 3!
i have had couple of problems and could have some complains..
-my sub does make things rattle and sound like something in the drivers area is loose.
-the motor mount sucks!
-squeeky noises inside the car makin me feel in my old project Integra
-5th gear blows we need a 6th to save some gas. 80 and above cars RPM are over 3500 which just wastes ur gas and can be annoyin if you have an exhaust.
-alot of break dust
-and the biggest problem i would sad was the reverse light switch which is clicked on by a spring the rod clicks when u put it in reverse broke leaving my reverse lights on for about 2 hrs non stop causing the housing to melt! so i had to take it to the dealer and order the part and im getting it replace but since i had them painted blk i had to take the paint off which was a b***ch and 12 bucks... (warranty covered everything so far. but the 12 bcusk for the paint remover s**t)
this was when it was messed up...

u can barely tell but the inside looks melted...

other than that i love my 3!!!
-im saving $110 bucks a month just in car payments (had a Nissan Frontier Crew Cab long bed)
-$50 bucks a month in insurance
-about $22 every gas tank
-and i get to enjoy a way smoother ride! so thats priceless!
gotta say i love my 3 by far the most fun car.. (s*** idk muddin in the frontier every weekend was too much fun)
