I love my new 245 and want to treat it well. The awkward bit is living on an island with the car street parked in the city. I will mostly use it for highway trips every two to four weeks with rare short city trips in between. The question is: for the best long term health of the car, how often and how far should I drive it to keep it "limbered up"? I know machines suffer just as much as people from lack of exercise, what would be a minimun exercise program for my car aside from standard mechanicals?

yours, martin
