There is one for sale at the moment:

Only £40K! However, I was talking to the owner of a 1929 Bentley 4 1/2 lites with VDP body work and he'd spent £40K last year on an engine rebuild (the Bentley would cost around £660K....). To be fair to the Bentley owner, who is a very nice chap, he does around 6000 miles a year in it including an annual trip from north of Inverness to London in about 11 hours so it's nice to see the car used.
Be thankful that we can indulge in our love (and occasionally 'hate') of a real British sports car for the price of a TV set.
