I wonder if Smart offers the Mercedes MB TEX vinyl-ish leather replacement. I've got that on my 2002 E320 and it hasn't shown a wrinkle, crack, or stain yet. It's comfortable and even slightly vented via perforation.

On getting shocked: I always "beat it to the punch". After getting out but before I touch the metal to close the door, I rap my knuckles against the metal. This way, I know exactly when and where the shock will occur; no surprises.

On buying new: The only reason to buy new is when it's a very special car that you won't find used. Mercedes AMG, BMW M, Audi RS, Chrysler SRT, and exotic sports cars. Or if you do find them used, there's a good chance they'll have been tortured on a track or moded beyond spec. Oh, how I wish for a spare $80,000 to buy that W211 E63 AMG wagon....

On 1986 Jaguar: Of course you had interesting problems, it's a true Jaguar.
