What NON-Mopar car do you most regret selling?

A few but the ones that quickly come to mind are a 1966 SS396 Impala Convertible Marina blue, white int. and top. Fully loaded GM executive vehicle. And next would be a 1969 SS396 Chevelle Convertible Marina Blue white int. and top not fully loaded but had A.C. power windows and locks. Pure chick magnets.
Here's one (of many) I let get away it was a little too rusty. About 69 or 70 a 1966 Mustang Convertible Bronze with a white top and int. with the 289ci 271hp & 4 speed for $400.00!
