The first and last station wagon in the series of Moskvich 3-5 prototypes (1973-1975 year of planned production). The car was planned to be assigned an industry index 2145.
The fifth door went up entirely. The documentation emphasized the increased capacity of the body compared to the Moskvich-427. Horizontal rear lights were used, the same as those on the Moskvich 3-5-3 sedan. The prototype was subsequently used for factory needs.
