Very nice looking car. The light interior, although a ***** to keep clean I bet, looks nice in the dark colored car.
I think 3.8's get a bad rap personally and it's likely the result of abuse. In my 3.8 that I purchased in March with 51K miles, I had heard that many of them take a beating at the Autobahn speeds (my car came from Germany to the US) and the owners do not always let the oil temps come up all the way before winding it out, or put crappy gas in the car. The rod bearings are thinner on a 3.8 as I understand it and that is where the abuse can be seen. I had the rod bearings replaced in my M5 as soon as I got it and sure enough, they were in poor shape. Here are the pics again for those that did not see them last time.

If you know someone who is an S38 guru (as I do here in Chicago, luckily) have them do the rod bearing job for you. As long as there is no crank damage or excessive wear, it's a swap job but a pain since you have to drop the subframe, support the motor from above, pull the oil pan, and do it from underneath. Like I said, not a job for an amateur S38 mechanic.
I'm also running the Landzer chip in my 3.8 and I'm happy with the performance improvement.
