There is always interest in cars that don't appear correct at first glance. That said, a lot of cars have been played around with over the years, and there is nothing wrong with replacing a blown 2200TC engine with a 2000SC one.
As for cloning; it's very rare these days, especially on classic cars. P6's aren't worth a lot, and nobody is going to go to the time and effort to clone one.. and how would you do it anyway? The DVLA sends you a notification that you're no longer the owner, should someone change the ownership of a vehicle, so that wouldn't work. If you just want to copy the number plates, you don't need the chassis/engine numbers for that.
Cloning happens on £1m cars to be driven around Goodwood, not £3k P6's to be driven to the local chippy.
