Kind of a wimpy collection with only 3....
We've owned the '71 for almost 12 years, and only take it out on nice, cloudless days.
The '02 is my "work car," and has over 214,000 miles on it, and still has yet to let me down.
We got the '10 on 7/1/2009, and have over 16,000 miles racked up on it. Easy to do, as nice as it drives.
They are all in hibernation right now, as shown in the picture.
