'85-'86-'87 4kq differences

[jknittle@sundown.sdsu.edu]

Hi all,

I have noticed an '85 4kq in the paper here.  I was wondering:

Is there any real difference between the years of '85 to '87 for the 4kq  I
know the engine is the same but how about the other things.  Any design
changes or problems which were recitified in later years or is an '85
exactly the same car as an '87 with 2 more years under the belt.

Also, I know there are have been a lot of posts on this already, but does
anyone have a good list of things to look for in purchasing a 4kq of this
model year ('85).  I will of course have a good mechanic check it out, but
how about quattro specifics, like if the differential locks really work.
What are the typical expensive/annoying things which go wrong?

By the way if anyone in the San Diego area has seen it (it's out on some
lot on Miramar road) I would appreciate a comment.

TIA

Jim
