Hello, I was thinking about buying a DMC-12. I wanted to know how reliable are the DMC-12's? If I found one with less than 50,000 miles that was in good condition, about how much money would I have to spend each year on maintenance and repairs? Also, what is the general impression of the DMC-12's reliability: Poor, Fair, Good, Very Good, or Excellent? Thanks in advance for your reply. - Bill
