Non-Mopar car you wish you had purchased?

I was up at a Texas boneyard last year or so, big pasture, all old cars. The owners grandkids had (probably 12 and 14 maybe) pulled out a Gremlin and dropped in what the yard help thought was a 401 Amc motor. They used it to "drive" the yard. I should have asked if for sale., but I caught myself!!!!
