my father has a 1967 Chevrolet Impala. unrestored. He got it when I was 13 and it was our family car until my mother passed away in the mid 70s. We lived in inner city Philadelphia, in an area easily accessable by good public transit, so we barley ever drove it, wich explains why its still running after all these years. I took it for an oil change for him recently, and It had 38,000 miles on the clock. I still cant believe that.
My dad is 89 and doesnt drive much, so that cars going to be on the road for quite some time!
