Going to trade my RX-8 tomorrow. Been in for rough idle and cutting off (in traffic) 9 times in 6 months. Mazda has no fix for this unreliable engine. They can only add engine mounts and brackets to the engine... yeah, makes no sense to me either. Beautiful car, horrible engine!!! Stay away from this car until they start putting a reliable engine in them. First 30,000 miles were wonderful, but beware - once you turn 30001 it goes down hill from there. Cold and hot outdoor temperatures play a big part in the rough idle as well. Again beware of this car. Don't lose money on it like I have.
Body and interior.
Stop putting the rotary engine in it. There is a reason other auto manufacturers don't use this engine.
