Right now I don' t have the time to check them, but I still own a Mercedes 190 SL, a Rolls Royce Silver Wraith(?) Convertible, a Ford Thunderbird Convertible, a truck, a Renault Caravelle and a tow truck.

But the tow truck and two 1967 Mercury Cougar-rubber cars are looking different. The have different wheels and IIRC they are not made by Tomte, but by a West German company.
