what is the rarest car you have come across

I bought a 1949 VW Hebmuller Caberolet aprox. 696 produced. out of a wear house in Navato Ca . not running had it running next day
bought a 1970 Monti Carlo 402, 4 SP, with skirts out of a wrecking yard in Maryester Florida with build sheet
62000 mi
rebuilt carb brakes re upholstered it original then painted

 

Triumph Mayflower I think... Some guy chopped it and put a 392 semi in the small thing. Saw it at Columbus Goodguys show.

 

for me it would have to be helping with the restoration of the Carrillo Roadster. I got to detail it here in this thread http://www.jalopyjournal.com/forum/threads/details-you-dont-normally-see.502186/

 

This car was advertised in Hemmings in 2000 as a 33 ford roadster. Had to go look at it.
It was a custom fiberglass car built in the 50's in California and made its way to Pittsburgh,Pa. It was built on a 33 Ford chassis. Had a flathead with a 2 pot Evans intake with dual strombergs. Also had very rare Harrell aluminum heads. Brass tag on motor said built by Competition Motors,Burbank Ca, Probably should not have sold it.
When I was in my 20's I worked for a guy that had a Pegaso coupe.I think 5 were made. He also had a Maserati GT 5000 that was once owned by the Shaw of Iran. Pretty rare stuff.

 

I once owned a 1966 rambler American convert, which is rare in it's own right, but it had a 290 4 speed, one of three made (and 25 290 autos.) it was the first year of the 290 engine and 623 cars had them-500 were special 2 tone Rogues. Some were even four barrels. (mine was a two barrel). Also owned a 74 Bricklin-only made just over 700 with the AMC engine.

 

I suppose I could also toss in this one, an Allied/Atlas Swallow:





Early '50s kit car (copied from a Cisitalia) that brings new meaning to the word "crude" but there were only about 35 built. The open cars were rarest with only a few built, but the guy from Forgotten Fiberglass says this is a decapitated coupe, so it's probably beyond saving. Anyone recognize the chassis? MGTD?

 

Your Atlas/Allied pseudo Cisitalia is similar to Bill Burke's own car in that he cut the top off when he repurposed it from running Bonneville to road racing. I think he said it had a V8-60 in it at that time.

I would think his car was one of the first ones with a frame built of elliptical tubing rather than being from another car.

 

MGTD frame here....looks like the frame in question was altered....

 

I have another car to add to the couple I've already posted. I picked up a '53 chrysler new yorker deluxe club Coupe about a year ago. It's one of 1934 built for '53.

 

I had one of those Chryslers too. same color. wrecked at 33K, put in a barn. engine missing. JJibs & I parted it out.

 

Guy here in town has a personal museum full of mostly Euro classics. He's got an exceedingly rare Isotta Fraschini.... worth a small fortune.
