It means it's a wagon. With fuel injection.

If the MB was treated as well as the BMW then you'll get the same result. If
not then well, uh, you won't.

You might notice the parts on the MB are a bit higher in quality. Look
at things like relays, wiring etc...

But, ya know, they're old German cars so expect idiosyncracies.

John,
This gives a high level overview of Mercedes reliabiliy, but does not
go into the individual cars within each class. It is the best I have
been able to find, and generally gives an accurate view of overall
model reliabilty for the major manufacturers. Good lunck.

PS - I had the pleasure of being in Australia for a few months last
year and had a great time. Both the people and country were terrific.
Was largely in Melbourne, but had a chance to see Sydney and some other
east coast cities. Enjoy the homelife!
