Third one is a Johnson Phantom, the OP car and the first two are one of the many built by smaller operators, quite possibly on used cars even.

The first one looks like it's based on a Cadillac,

second one a Chevy Caprice,

Third one is a Chevy Camaro base.

Excalibur Phantom?

Yeah, that's what bugs me either - a sedan, but no Lincoln or Cadillac. This might well be something coachbuilt by Rage (= Knudsen reloaded) or Baroque Motorcars or Elegante Coachworks Ltd. of St. Louis, Missouri.

I don't know many that were based off a Crown Vic/Grand Marquis 4-door chassis from the mid-late 80s. Most used a 2-door chassis of a Cougar or Regal from that era.

Cool car! I don't think it's a Zimmer, but a similar conversion riding on the Neo-Classic-wave. The front fenders remind me of the CMC Classic Tiffany, but it isn't one of these either.

I'm planning to start a major Neo-Classic identification project at some point here on IMCDB and once the time is right (to be honest, I'm a bit afraid on my own behalf of opening that can of worms...), I will look into this one as well - that's all I can do for the moment.

Last summer I went to Europe with my family, and I came across this car. It looks like a Zimmer, but it's much longer than most Zimmer's. Can anyone tell me what car that is?!
