"ARWadsworth" gurgled happily, sounding much like they were saying:
Not quite. There's rather more to "a car" than a couple of easily removable panels.
'erself still owns her first car. It's been rebuilt onto a galvo chassis. The rear end of the body and windscreen surround panel have been replaced. All four wings have been replaced. The floors and sills were replaced years ago. It's on it's third or fourth roof. The seats are in need of retrimming. It's been fully resprayed. All five wheels have been replaced with new.
The suspension, engine and box are all still original, as are all four doors and the bonnet. The original (and unresprayed) bootlid's sometimes used, sometimes a different one.
Is it the same car as the 18mo low-mileage, one-owner car her father bought her in 1984? I'll let you discuss that with her...
We won't even go near one of the long-term projects - which was rebuilt many, many years ago around a chassis/engine/box/suspension from a different model of car, and which is currently having the entire steel frame replaced with new, and which will likely end up with a mix of the (presumed) original panels, some from another car plus some new.
Then there's another one of the fleet, which was heavily rebuild a few years ago. The identify seems to be a couple of years newer than the actual vehicle, but it's difficult to be sure. The engine's the higher power version from a different model, and the shell was certainly made from almost entirely new parts, as well as a new chassis being modified to suit.
Then there's one we sold a couple of years ago - new chassis to a quite different design to suit the heavily re-engineered and modified drivetrain and suspension. Larger capacity engine from a different model. Bodyshell changed for a better one. DVLA inspected that, and were quite happy to let it retain the original VIN & reg - although that's academic, since it's been exported.
It only becomes naughty if you tell fibs in order to try to make money by passing something off as something else.
