Wow, thanks for the detailed responses guys!
Now I know how Mercedes labels their diesel cars . . . it never made sense to me before. I guess I was incorrect to say that SD stands for "Super Diesel" . . . what is meant is S-Class Diesel. This makes sense seeing as my Dad's car is a 300SE (the E stands for gasoline) where as, if it were a diesel, it would be a 300SD . . . totally makes sense now :)
Also, thanks for all of the detail regarding car repairs. It's just that I saw this 300D Turbo (I guess it is a W124 E-Class Turbo Diesel?) for sale for $3999CAN ($3000US) in my area, and thought that it looked like a good deal (depending on the mileage of course, which isn't listed). My brother-in-law is looking for a good cheap car to run, and I thought that this might be a good choice. Naturally, he doesn't want to spend much on repairs, and I know that repairs on a Benz can be costly.
Could you guys have a look at the Ad and tell me what you think? How many miles should it have in order for this to be a good deal? Also, remember that this is a Canadian ad (so it is actually $3000US).
