On your number 4, did you mean the Chrysler's TC by Masarati? I don't remember any Chrysler/Masarati Labaron GTC. But there was that clumsily named Chrysler's TC. The body was close to, but discretely different from, the Lebaron.
I mostly agree with your picks (TC/GTC included), with a few exceptions. The Allante was a market failure, but a good Caddy (especially compared to the domestics of the day). Your rental 1.0 L Swift clearly was a dud. I just have too many fond memories of my friend's Chevy equivalent, which ran well and actually handled fairly decently - hell it weighed like nothing (which also made it fun to pick up and carry onto the sidewalk for a prank with a couple of other friends). Also, any such list should include the Gremlin, Mustang II (grabs anti-flame gear), and Pontiac LeMans.
