-This is a well known sales add. This car has been for sale for at least a year. First in Germany, then in the Netherlands and now in Germany again
(from the same dealer). The mileage is in fact above 20.000 km (19.900 km just sounds better). No doubt a good car in a good shape.
The VIN is known. It is NOT a 6-speed, although is has the upgrade package offered by BMW to M5/M5touring owners with a 1992-1994
model year car. It is not sure if the car has the compound breaks upgrade but it does definately not have the 6-speed-gear-box.
The car was apparently purchased by the car dealer on speculation, although he had stated to purchase the car for his private collection.
The car has only had one owner/user exept for the involved dealers.
There already exists a 'thread' for this car here, also telling the VIN. I will try to look it up and place a link here.
