Tim- Sounds like you found a nice one! I keep my '85 635CSi in storage pretty much throughout the year, only occasionally bringing it out on sunny days (here in the Seattle area we only get about 2-3 months of reliably "nice" weather each year). I take it out at least once per month, and whenever I do I follow the "20/2000" rule: at least 20 miles @ 2000rpm (or greater). LOL!
