* These 2 photos are of GAZ-12 "ZIM" that has been put on narrow gauge railroad chassis and served for years as a personal railroad trolley of some railroad chief. According to records, this unusual combination of auto and rail has hit 3 persons and innumerable amount of horned cattle. (Obviously, very few of the technical parameters listed here apply to this vehicle).

** The cabriolet did not have a special index denotation because very few of them existed; perhaps only 3 vehicles.

This was one of the first Soviet limousines. However, this model also had an ambulance modification, whose technical characteristics were somewhat different from those of the limousine version. GAZ-12 had a climb of 24 degrees in front and 18 degrees in the rear. "ZIM" is an abbreviation for Zavod Imeni Molotova (Plant named in Molotov's honor). Also a few cabriolet cars were made, but never produced serially. GAZ-12B ambulance on the other hand was on serial production. It had a glass partition behind the front seat, sliding-out stretchers and two folding seats. On the front part of the roof was a red cross lamp and on the front left fender was a spot light. 

Here are a few photos from 14 November 1999. [the date on photos is different because Maxime must have forgotten to change the time after he came back from Russia]. In it you can see Maxime's 1968 GAZ-M-21Volga and Tim's 1959 GAZ-12 ZIM. Tim's ZIM has GAZ-24 engine, which appears to be a bit too weak for such a heavy car.
