I bought mine about 10 months ago at Pete's. They'll be gone soon. Brown Motors in Greenfield was very good for service on a couple of Jeeps, no BS and fair prices. I don't know how they'd so with a Crossfire though. Fortunately, I haven't had anything that I needed to go back to the dealer for. Another possibility for service (not warranty) is Donovans on Rt 7 in Lenox, they seem to be great with high end cars and i'm sure they'd be up to snuff on the Mercedes mechanicals. Could be worth a call anyway...
