I thought that the Lincoln Mark VII was the only Ford that got the BMW turbo diesel...IIRC that was only for a year or two in the mid '80's. But, maybe you could get a T-bird/Cougar diesel in Canada?Wasn't that the engine that some mercury cougar/T-birds used in the mid 80s? Saw one on kijiji a while ago.
Think I'll pass on a diesel with a rubber band on it though. Chain or gears only and hope to god for an iron head. All the more reason I want to find out more about the 300D/300TD.
And, FWIW, the VW's aluminum head and timing belt are why I opted for an M-B instead of a VW when I was first looking for a commuter car in '02. Any M-B built during or before the 1985 model year (except the '84/'85 190D) will have an iron head. They'll run forever if you treat them right...on both of my prior M-B's, the front suspensions wore out long before the drivetrain had any problems On the second car, the front suspension was bad enough that it would chew a new tire down to the metal band in less than 10K miles so, when the tranny lost Reverse and a friend offered $700 for the engine, I couldn't say no...and, that engine's now in its 3rd car
At the risk of self-promotion, take a look at the two threads that are stickied on the top of the Mercedes forum on this site. Might help to give you an idea of what's out there and what you may be looking for.
Hope that helps some I admit that I'm ******* after a new TDI but I love the M-B diesels...I would recommend one to ANYONE who's mechanically inclined and on a tight budget and/or wants cheap reliable transportation. If you want a car that's perfect in every way, an M-B can nickel-and-dime you to death, but for basic reliable transportation that you can repair yourself, they can't be beat IMHO
