I'm looking at an '85 635 European model found on the internet. 70,000 miles, great cond., $9,300. Is this a good deal (from what limited info. I can provide)? And what exactly does the european add compared to the US models? I know the hp is up a bit. Does it have the same safety ratings and construction specs, and what about performance? What about servicing and parts availibility? Will I be disappointed with this model? Excuse me for all the questions -- I'm European-illiterate.
