I just resurrected my 92, after getting another care (MB 300CE) and sticking the SVX into a garage with a cover on it. The transmission was grumbling a bot, and I thought I'd have to get (yet) another.
Surprise .. tranny is fine. New MAF, new valve covers, and an ECU and TCU from ECUtune, and I am one happy camper. Hard to believe this, but it runs like new, and better than when I obtained the car.
I am glad I took the time and spent the $$
