I have owned this car for about 6 years. It had 47k mile when I bought it. I drive this car very hard and I have 164k mile on it. I know this is crazy but I have never replaced the timing belt (not recommended). I have had to replace the O2 sensors but that is about it for repairs. It has a good ride, smooth transmission, and good pick up (especially in PWR mode). This is the best car I have owned.
PWR Mode - Smooth Transmission - Reliability
All four O2 sensors went bad in the same year but this does not cause the car to stop running. More horse power in the GS 300.
