Hey Steve!
My Eldo was fairly fast, but it had the fuel injection so that may have helped. It was a very heavy car, so the engine still seemed underpowered, considering it was a 500 CID engine.
The yellow and white Cadillac is a 1955 Coupe de Ville.
I loved my 77 Coupe de Ville! It WAS fast! And a fun car to drive. It was a full sized car, but handled like a much smaller car. I finally sold it at 198,000 miles. It never used oil, and the body never rusted. I sold it for $2800.00 in 2000.
Post away. If you have something, throw it up!
