14.3. Purchase of the old car or mysterious set of figures and letters


Acquisition of the car – an event considerable in life of the motorist. Questions which rise at various stages of its implementation are so extensive what to try to capture it within one material is not reasonable. Therefore we will try to cover one topic: "Acquisition of the used car".

There is a lot of ways of purchase of cars. If you want to buy the used car, it is possible most to go behind it abroad, independently and as a part of special tourist group. With smaller efforts you can buy the car according to the newspaper announcement or through acquaintances, and also in car showrooms and on car markets. Everyone their these ways has the features, but below the following recommendations are similar for each of them.

So before legally making out purchase of the car, it is necessary to check existence of all relevant documents. At the same time it is desirable to use such service as check of the car on stealing. These services exist now not only in offices of the State traffic inspectorate, but also in many autoshops and on large car markets. Upon purchase of the car with foreign numbers, in particular from the Baltic countries, to the required price it is necessary to add quite considerable sum on its customs clearance. Upon purchase of the car from the Kaliningrad region pay attention to a mark of customs in technical data sheet which can be valid as for Russia, and only for the Kaliningrad region. In the latter case you should dorastamozhivat the car.

The main document on the car is the passport of the vehicle. Issue of the technical data sheets and technical coupons of an old sample (approved by the order of the Ministry of Internal Affairs of the USSR N370 of 15.10.82) is stopped since January 1, 1994. Earlier issued passports admit valid. But only for this year our experts faced three times that on the cars offered to sale the passports of an old sample issued allegedly in 1995-1996 were shown. We advise to refrain from acquisition of cars with such documentation. Purchase of cars in which registration certificates there are such records as/N (without number) of or the N/at (is not established), is also undesirable.

The order of filling of technical data sheets is defined by "The instruction on filling of passports of vehicles". We provide from it, in our opinion, most necessary information.

First of all is an interpretation of identification number (VIN).

The first part of the VIN code consists of 3 figures or letters designating a geographical zone, code of the country and a code of manufacturer of the vehicle.

The second part of the VIN code consists of 6 figures or letters designating the vehicle according to design documentation.

The third part of the VIN code consists of 8 figures or letters designating serial number of the vehicle. The first sign consisting of a letter of the Latin alphabet specifies for a year of release of the vehicle.

For example, identification number of the VAZ-21013 car has the following designation: XTA 210130D00000002, where X – a geographical zone (Russia), T – the code of manufacturer (And – VAZ, In – AZLK etc.), 210130 – model or modification, D – year of release (1983), 00000002 – serial production number.

For designation of year of release of vehicles the following letters are established: D – 1983, E – 1984, F – 1985, G – 1986, H – 1987, J – 1988, K – 1989, L – 1990, M – 1991–1992, P – 1993, R – 1994, S – 1995, T – 1996, V – 1997, W – 1998, X – 1999, Y – 2000.

Visually defined color in which the vehicle is painted is specified in a line of the registration certificate "Colour of a Body (Cabin)": white, red, yellow, green, blue, brown, black, multi-color etc.

The name of enamel on marking of manufacturer is specified in the line "full name of color of a body (cabin)".

At change of color of the vehicle in the passport the corresponding record is made.

There is a mass of ways of falsification and forgery. In practice kill (and respectively bring in the document), as a rule, one figure in number. But to tell on pages of the popular edition about subtleties of technology it is represented inexpedient. And hardly the person who for the first time took the document in hand will be able to reveal forgery and to pay attention to discrepancies. Therefore most check of the car on stealing in GAI not only verification of numbers with data of the computer, but also verification of documents is reasonable. And still at visual survey of numbers on the car and documents we advise to pay attention on:

 – compliance of fonts and their inclinations;
 – an ootvetstviye and sequence of terms and dates in records;
 – lack of erasures and violations of a protective grid;
 – readability of prints of the seals.

Especially this question is particularly acute concerning documents on the cars which arrived from Poland and the Baltics.
