That is a great price if it is a clean SRT. Some of the more common issues are IC pump, crankshaft position sensor (CPS), faulty solder on the RCM. The IC pump is about $120 IIRC, CRS about $40, fix the RCM yourself for nothing. These are the main ones that seem to come up alot. I have had to replace the CPS, but that is my only issue to date. These are well built cars that are pretty trouble free. Maintenance wise, all of the mechanicals are Mercedes as it was built using the SLK32 platform. The main thing maintenance wise is that it takes 8.5 Qts. of Mobil One 0W40 Synthetic oil and a fleece filter to do an oil change. Dealer charge for an oil change is about $120. Most people here do the oil changes themselves, but it is still not cheep. Having said that, the oil is changed every 7,500 miles, so you will not be changing it that often. If you have it as a weekend driver like I do, you would probably just change the oil once a year.

It has been said many times on this forum, but the SRT is probably the best value on the market today for a performance car.

Good luck, and welcome to the forum.
