What's a good year for an SL?

[rob_in_boston]

Thinking of trading in my BMW for an late model to vintage SL. Are there years to avoid? My requirement list is:

cool looking
reliable
It doesn't need to be a high performance machine.

And I'd like spend less than (yikes) 10K. Looking at ads in the The Star and else where show this is possible for 70's and 80's vintage.

Any help would be great.
