I'm waiting to hear back from the dealer today to go look at the Crossfire again, looking for things you guys pointed out in this thread. Like the condition of the top, checking out the antenna gasket and trunk area for leaks, among other things.

I have done my homework, and two things stick out. One, on the CarFax report, it shows the NYS Emissions Inspection failed 5 different times over the span of nine years. Then, after another 50 miles or so, the report, sometimes a day or two later, at times the same day, shows the car passing the inspection. Have there been any emissions issues with the 3.2L Mercedes engine?

Second, not to sound like a broken record, but just about everyone I talk to about the car has told me, "With a Mercedes engine, you have to take it to a Mercedes dealer" for an oil change. I watched a YouTube video that showed the top mount oil filter unscrewed usually by hand, removed, and then you remove and replace the paper cartridge and three O-rings with a Fram or other good name cartridge. This video shows the oil being sucked up the dipstick opening using a marine-type oil suction pump.
