Re: Looking into getting a local SRT-6. Questions
I think I have seen one post on failed supercharger in the last 10 years. The SRT6 engines are built considerable stronger than the n/a engines to handle the extra power and heat. The intercooler pump is a known weakness and it looks like the owner took care of it. These are basically 2004 SLK 320s under the body, and M-B makes a pretty reliable car. While electronics can fail, there has not been much talk of it on the forum. I have only had a shift linkage cable pop off, eliminating 1-2 gears, but it was reconnected and adjusted for $140 and now shifts better than ever. Bought the n/a new in 2005 and the SRT6 in 2008 (8500 miles; now 24k) and other than fall oil changes prior to winter storage and tires and a battery each, no other maintenance. A careful test drive with your ears open will reveal a lot. Any 10 year old hi-po car that has been abused will clunk or make unusual noises. If it has been driven hard but with care, it should be fine. It's tough not to make a WOT run at least once while driving, but unless you are doing this constantly it should be fine. And running high speed -- the car is built to cruise over 120 mph and I have [allegedly] touched 150+.
