What NON-Mopar car do you most regret selling?

'57 Fairlane 500. Had a 351C in it but the old 312-4 purred too. Was actually very light for what it was. Ugly headlights (57 DOT lighting law prevented it from having its designed quads like the 58) but it had style. Mechanicals were good. Just got tired of its 4 doors and C4 trans breaking (3x) behind that cammed Cleveland. had great 427-8-9 potential. '71 Honda AN600 sedan. 45hp of raw 2 cylinder power in a Jap Mini replica. Parts were already N/A in 1984
