[Porsche-O-Phile]

I bought one on my M.B. When I bought it. Not bad but not great. I never broke even on it and I doubt I'd get one again. It was peace if mind in case the engine or diff. ever decided to go kaboom, but that's about it. Clutch was excluded (although I haven't had any reason to replace it and I'm about three years out of warranty now). I did get several sensors replaced - one thing that really irritated me was having to fight with the warranty company over the type of parts used in the replacements. They always insisted on cheapo aftermarket and I insisted on factory / O.E. only. I usually got them to split the difference with me, but I'd be especially wary of any policy that doesn't specify the type of parts or outline procedures for "upgrading" to whatever you want.

All-in-all it was good peace of mind but unnecessary. I wouldn't do it again. I only got back about $0.35 or so on he dollar.
