Abstract: 1. Transformable passenger car comprising a framework and a body having the front part, the middle part and the rear part with a seat, characterized in that the rear part of the body is executed a modular assembly and has a basement comprising a rear drop side and two side wings, and a detachable module fixed on the basement by means of a separable joint, said module being capable to get removed or changed without infringement of normal functioning of the car and constituting a cowl having a roof, side walls and a rear door, whereas upper butts of side wings and of the rear drop side of the basement, butts of the middle part facing the detachable module, and butts of the cowl are all of them provided with mating surfaces executed in the form of profile elements shaped as grooves in case of the cowl and as flanges in case of side wings and the rear drop side of the basement and butts of the middle part, a resilient seal being placed between grooves and flanges, and the seat being capable to get transformed and placed vertically in the middle part of the body. 2. Transformable passenger car according to Claim 1, characterized in that all body parts thereof are made of a polymer composite material. 3. Transformable passenger car according to any one of Claims 1-2, characterized in that the cowl is executed as an integral carrying unit, its roof and side walls constituting a single U-shaped panel, the rear door being hinged thereto. 4. Transformable passenger car according to Claim 3, characterized in that the U-shaped panel comprises the outer facing part and the inner reinforcement part connected to each other by means of adhesive joint, longitudinal and transversal stiffening ribs being provided on the reinforcement part surface, and metal plates being placed between the reinforcement part and the facing part at locations where the rear door of the cowl is hinged to the roof thereof. 5. Transformable passenger car according to Claim 1, characterized in that the seat comprises two locks, each of them being fixed with its one part to the corresponding side part of the seat back, and being fixed with the other part to the corresponding bracket, of which every one is fixed to a side wing of the rear part of the body, the middle part of which has a cavity for placing the seat in transformed vertical position, while the seat has two hinges, each of them is fixed with its one plate to the lower surface of the seat cushion, and with its other plate - to the floor of the rear part of the body. 6. Transformable passenger car according to Claim 1, characterized in that it comprises a partition fixed between the middle part and the rear part of the body and having surfaces mating butts of the middle part of the body said surfaces being executed in the form of profile elements. 7. Transformable passenger car according to Claim 6, characterized in that the profile elements of the partition are executed in the form of grooves, a resilient seal being placed between grooves of the partition and flanges of butts of the middle part of the body. 8. Transformable passenger car according to Claim 7, characterized in that the partition comprises the inner reinforcement part and the outer facing part connected to each other by means of adhesive joint. 9. Transformable passenger car according to Claim 1, characterized in that it comprises at least three modifications of detachable modules representing "estate car", "van" and "hatchback". 10. A method of transformation of a passenger car lying in that the framework is being preliminarily mounted, then the body is being fixed to the framework, said body having been executed with front, middle and rear parts, a eat being installed in the latter, and then the car is being transformed from one body modification to another one, characterized in that a common framework is being mounted for all body modifications, while the rear part of the body is executed as a modular assembly comprising a basement and a detachable module, into the grooves of which, in the course of transformation of one body modification to another one, flanges of the basement are being inserted, then the detachable module is being pushed in along the grooves up to the stop at the middle part of the body and up to getting flanges of butts of the middle part of the body into grooves of the detachable module, which is then being fixed on the basement by means of a separable Joint, or the said operations are being performed in a reverse sequence. 11. A method of transformation of a passenger car according to Claim 10, characterized in that transformation of the seat from the rear part of the body to its middle part or from the middle part of the body to its rear part is being performed, for which purpose the seat back is being released from fixation on brackets of the rear part by means of locks located on sides of the seat back, which is then being folded onto the seat cushion, and then the seat is being installed vertically, in folded state, in the cavity of the middle part of the body, or the said operations are being performed in a reverse sequence. 12. A method of transformation of a passenger car according to any one of Claims 10-11, characterized in that a car of the "estate" Body modification is being transformed into a car of the "landau" body modification, the separable Joint of the detachable module of the "estate" modification being released from the basement, flanges of the basement being pushed out from the grooves of the detachable module, and the detachable module being removed from the basement, thus forming a car of the "landau" body modification. 13. A method of transformation of a passenger car according to Claim 12, characterized in that a car of the "landau" body modification is being transformed into a car of the "pick-up" body modification, transformation of the seat from the rear part of the body to its middle part being performed, for which purpose the seat back is being released from fixation on brackets of the rear part by means of locks located on sides of the seat back, which is then being folded onto the seat cushion, and then the seat is being installed vertically, in folded state, in the cavity of the middle part of the body and then a partition is being installed between the rear part and the middle part of the body for which purpose flanges of butts of the middle part of the body are being inserted into grooves of the partition, and the partition is being fixed by means of a separable joint to the basement, thus forming a car of the "pick-up" body modification. 14. A method of transformation of a passenger car according to Claim 13, characterized in that a car of the "pick-up" body modification is being transformed into a car of the "van" body modification, flanges of the basement being inserted into the grooves of the detachable module of the/van" body modification, the detachable module being pushed in along the grooves up "to the stop at the middle part of the body and up to getting flanges of butts of the middle part of the body into grooves of the detachable module, which is then being fixed on the basement by means of a separable joint, thus forming a car of the "van" body modification. 15. A method of transformation of a passenger car according to Claim 12, characterized in that a car of the "landau" body modification is being transformed into a car of the "estate" body modification, flanges of the basement being inserted into the grooves of the detachable module of the "estate" body modification, the detachable module being pushed in along the grooves up to the stop at the middle part of the body and up to getting flanges of butts of the middle part of the body into grooves of the detachable module, which is then being fixed on the basement by means of a separable Joint, thus forming a car of the "estate" body modification. 16. A method of transformation of a passenger car according to Claim 12, characterized in that a car of the "estate" body modification is being transformed into a car of the "hatchback" body modification, the separable joint of the detachable module of the "estate" body modification being released from the basement, flanges of the basement being pushed out from the grooves of the detachable module, the detachable module being removed from the basement, then flanges of the basement being inserted into the grooves of the detachable module of the "hatchback" body modification, the detachable module being pushed in along the grooves up to the stop at the middle part of the body and up to getting flanges of butts of the middle part of the body into grooves of the detachable module, which is then being fixed on the basement by means of a separable joint, thus forming a car of the "hatchback" body modification.
