I agree on the extended warranties. Like I said, I have sold A LOT of them and made big bucks---more than double my money at the dealer level---standard in the industry---a $700 policy is sold for $1500 plus---It's called "back end" money. I had my reservations, but with the supercharger costing 6k new and 2k rebuilt PLUS labor and all the other AMG only parts IC, beefed-up trans, etc---I took the shot at 2.9 cents per mile. My car was 5 going on 6 years old when I bought it---only 900 miles but still had the age. From my days in repair, A/C problems start about 7 years or so and definitely by 10 years---no matter what the miles are. A/C systems are under 75 psi even at rest---Called static pressure. My guess is I will get my money back just on the A/C alone before 11 years since built---MB's A/Cs are not cheap. And although it sucks, no other high performance manufacturer gives a 7/70---Not Porsche, AMG Mercedes, BMW Ms, etc---and their cars cost even more. Chrysler was in line for this type of car---Actually, MB made that decision, I'm sure! Just the cost of "the grin"---permagrin that is!!! Let us know about the dealer and check to see if the nuts were turned on that 50 amp fuse. You will see marks from a wrench!!! Good Luck---Jimmy
