Several of mine come to mind, and a few weren't Mopars...
Red/white '68 Charger 4-speed, a couple of the 383 RRs, a Q1 Hemi/4peed RR, a Z28, a '69 Mustang FB, and especially a '73.5 911.
That's the short list.
But I suppose if I'd kept them all, I'd need 10,000 square feet and I'd be sleeping on the floor.
I take some pleasure in knowing I owned and experienced them, but it's still bittersweet to ponder...
