Clearly, I don't qualify as a "car guy". I'm 58. I still own half the cars I ever bought.
1978 Plymouth Arrow (Mitsubishi) [Bought new, traded in with 192,000 miles on the clock.]
1987 Pontiac Grand Am [Bought new, sold with 135,000 miles]
1999 Chrysler 300M [Bought new, still own, 170,000 miles]
2006 Lotus Elise [Bought used; had 17,000 when purchased, now 70,000 miles]
I suppose you could add one to the list. It's the "hand-me-down" car that was never titled in my name:
1967 Chrysler Imperial Crown [Sold with 145,000 miles, but I probably only logged the last 15k]
