Not that I know of. However, with only 250 Cabrios made in 1955, anything is possible. Cabs are much more rare than Speedsters and Coupes.Is/was that your car?

That used to come from poorly vented gas tanks and fuel expansion once it comes out of the ground at around 50°.Looks like someone either needs a new gas cap, or some practice at the pump.![]()
