Oldest was the 1968 Chevy Impala Custom that my folks handed down to me when I was in high school. Couldn't burn the tires on that old girl but she past many a sports cars that were 20 years newer. Willy was its name...on the road again...

Longest was the 2009 GMC 2500 that I just replaced last year, so 11 years old with 138,+++ miles on it.
