What NON-Mopar car do you most regret selling?

My 1967 Pontiac GTO, all original big block car. Single 4 barrel but the higher horsepower with an automatic, but it had the Hurst his/hers shifter. Black plate car here from California. It was gulf turquoise exterior with a turquoise interior. Beautiful car, sold it to put a roof on my house! Of all the cars I've had and sold, that one kills me.
