I found a very nice 1994 Mercedes S350TD for sale and am considering buying it. It has a little over a 100K miles. It's the last of the big body Mercedes diesels that were imported to the US. Quite a big car at about 5800 lbs with the leg room of a limo, double window glass for a quiet interior and much less plastic than in current CDI model. I took it for a short drive. Smooth handling but poor acceleration. Once up to speed it cruises effortlessly. The other used diesels I'm looking at is a 1999 300TD which go for about $20K and I've test driven a 2005 CDI which has incredible acceleration but it's price is $42K.

Anyone have some experience with the S350TD model? Seller is asking $18K Should I buy it?
