I have a 2004 RX8 with 83K miles. The car won't crank after it warms up and I deal with that. I took it to a nearby shop because someone told me my rear wheel was wobbling. These guys kept my car for three days and I finally went up there. The engine sounded completely different and would not crank at all. I had it towed to a Mazda dealer and they tell me the car is no good. What? Even if the engine is replaced? Why?
