It's a 5 cylinder turbo diesel sedan. The owners thought it was done for at 300k miles when the alternator locked up and the engine wouldn't spin over.
I cut the belt, got some new fuel into it and it started right up. When I get the chance I'll install another alternator and see how roadworthy it is.
I am a fan of GM 425,472,500 Cadillacs and 3800s and Dodge slant 6 engines but these w123 diesels are quickly earning my respect!!
