Thanks for the replies. I have the car for the week. It is going to a local MB mechanic this week for a bumper to bumper exam.
The car does need motor mounts (I assume) as the motor rattles/shakes when turned on/off, and has a light vibration. I have not confirmed the wiring harness, but it would appear to be original to me.
I noticed a fuel leak from the belly pan when I started the car...it had been sitting for two months. Owner says they never noticed a leak in the past, and I take this to be true. They are willing to have these issues repaired (aside from wiring harness, was not discussed).
The interior wood, seats, carpet, radio, electronics, sunroof, power seats, etc are all in excellent shape. Body/paint looks great. Car has never been wrecked. He did have the car repainted (white), from the top down to repair a few dings chips and color match the bumpers. The bumpers and side skirts are all white. Looks really sharp. Drives, handles, brakes, steers, shifts, excellent.
I must say I am surprised at the lack of power on hills. A running start or manual down shift gets it done. Not a big concern, just an unexpected observation.
I like the car, and feel it is a solid, nice vehicle. I simply don't want to be unrealistic on the purchase price. If I can get the car 100% up to par, down to a brake fluid flush, etc, I am thinking $8500 is a do-able price...
Thanks again for the input.
