I read another review someone wrote and I agree.
My transmission seems to lunge into second and third gear and my brake vibrate something awful.
This car is enjoyable although I have those few troubles.
Regarding your brakes vibrating, have you considered having the rotors turned? At least take it in and have a qualified mechanic look at the brakes. Most likely the rotors are warped and just need to be turned. This is not an expensive procedure.
