Just bought it with 64k miles. It seems in good shape, no obvious oil leaks, body is straight. It does have a lot of black thick oily/dust residue on the valve covers. Is this caused by leakage from the valve cover gaskets ?
Any pointers on what maintenance items I need to check ? It seems to maintain engine temp very well, doesn't ever get too warm. Oil pressure varies from 36 to about 48 PSI depending upon RPM. Shifting is very smooth even forward to reverse. It has had the throttle position sensor replaced and the tachometer by a local shop. Ran much better after that. AC is very cold and some liquid drips from the big silver canister which I believe is normal. This vehicle has had regular oil changes for the last two years at least. I paid $9500. Do you think I got a good deal ? Leather and all the options.
