As much as I dislike being cynical, there are a couple of sentences that don't gel.
I bought it in 1999 from my very dear friend after his wife died – he had bought it for her new in 1990
Further down, she says:
A Certificated VMC mileage check and full history search was carried out by Mercedes Main Dealer Carols of Wolverhampton, prior to the transfer of the vehicle from the first lady owner to myself.
All MOT certificates from date of acquisition to present date showing year on year genuine mileage.
I'm surprised by the lack of paperwork from the first owner, her very dear friend, and I wonder about the bootlid replacement. Does the rear bumper look a slightly different shade?
If the car is as described though, it's very cheap, and better still, it's called Vera!
