Hi Mark @rokgod

Whilst it’s true that all the Jaguar built Cabriolet’s started life on the factory floor as Coupes they were all registered as Cabriolets – we have the range of VIN Numbers for these.

A number of companies converted Coupes themselves into early Convertible and some as Cabriolets (using Jaguar parts).

I’d be interested to see some photos of your car, and see what we can find out for you about its history.

Cheers

Laurence
