I bought this car about 1 and a half year ago. Love the car, but here is my question.

When I got it, the left rear tire was absolutely bald ... the front two were like new and the right rear was worn slightly. The tires were on the factory aluminum wheels, so I thought the left rear wheel might have been warped. I had 4 15" 10-spoke wheels and I had 4 nearly new coopers. I had them mounted and installed on the 240. Now, I have driven it very little over the time I have had it, but once again I have the left rear tire into the wire (more on the inside but pretty smooth all over) and the right rear is worm slightly....front two again are like new. I did a little calculating and have put a little over 9k miles on it -- that's all. Would the rear trailing arm bushings do this? what could be some other problems? Frame being warped come to mind and it makes me sick. It has wear patterns like the rear end itself is crooked relative to the front.

Anyone have this come up before? Any help, as always, is appreciated.
