Hey,

I am from Germany and
I am planning to buy a 1977 mercury grand marquis:

What are the problematic parts on the car, what to especially look at,
is rust a problem with this model, are there workshop manuals worth buying...

Any hint on how to prepare for the eventual buy would be appreciated...

Greetings from Germany
