This is a fine looking example of the scarce blue model. Whilst there has been some addition of silver super-detail, a revision of the interior and the blue paint does look very fresh, the base has not been removed and the car is otherwise all original (apart from the windscreen replacement). The base rivets are untouched and the paint on the inside of the chassis is the correct blue colour.
I believe this to be an original issue with some additional paint applied.
