The thing with the cracked bumper that makes me wonder, why was it not repaired? As stated earlier, a car that nice should be taken care of right away. It sounds as if the owner had a slick car, drove it hard, messed it up, and couldn't afford to fix his **** up. That alone would make me not buy it. If he didn't have the ambition to get the crack fixed, who says oil was changed regularly, or brakes, tires rotated, fluid flushes?
And the TA, for the age, is ****ing mint. There are cars less than half that car's age with terible interiors and banged up bodies. I'd jump on that just for the condition of it. A nicely tuned TA can turn quite a few heads. Not as many as the BMW, but it will definitely garner some attention.
