1. S-class Mercedes-Benz
Model 190, with love called "kid Benz", was made from 1982 to 1993, but also now it not seems old. It became the answer to release by BMW concern in 1982 of completely processed 3rd series. Both cars – representatives of middle class and direct competitors. The new class C which has come in the stead series 201 in 1993, in a bigger measure personifies quality of production of Mercedes.
As to cars of the new class C which has come in the stead to the 190th model, these cars in many respects differ from predecessors to the best. Their bodies serve without any problems till present time. The full serial equipment (adjustable seats, ABS, a safety airbag for the driver) provides pleasant driving and safety. But also in these cars there is a number of shortcomings. So, in some cars of release of 1994 there is an aerodynamic noise because of bad adjustment of locks of forward doors, and in release cars till May, 1995 – a fragile hook clamp of a cowl. In January, 1996 of 545.000 cars it was withdrawn for defect elimination.
Fabric covering, as well as in cars of the previous generation, gloomy. Behind there is not enough place for passengers, forward seats in some cars of release of 1994 (it, however, is easily eliminated with simple greasing of the corresponding elements) creak. Only in few cars (about 3 percent) release of the same 1994 the covering of internal handles of doors departs. Besides, the scratch and a gnash are heard when lifting glasses of forward doors in cars of 1994-1996, in particular, in a hot season (it is eliminated in December, 1995 with a way of replacement of a directing sled and greasings).
Assembly of salon of cars of the S-class is executed carefully, only separate ordinary-looking plastic details spoil impression a little. In cars of all years of release a sled of the hatch of a roof is badly adjusted, emergence of scratches in operating time of a drive of the hatch is possible. Besides, in all cars there can be a noise at work a zaslonok of system of ventilation of salon, and also deformation (swelling) of the top part of plastic at the basis of forward lateral glasses after 1–2 years of operation. The last phenomenon is especially characteristic for cars of release of 1993.
In cars of 1994-1995 it is established trudnootpuskayemy (especially in a cold season) the lever of the parking brake. It occurs because of too thick layer of a corrosion-resistant coating in the lower part of a body that causes bad moving of a cable of a drive of the lever. In the spring of 1995 cars were withdrawn in a sale place for shortcoming elimination. In general, shock-absorbers, disks of brakes and especially coupling show durability much above the average level. Upon purchase it is necessary to mean that the hydraulic booster should be serviceable, differently his replacement will manage in a round sum. A steering wheel too big in cars of all years of release.
Have shortcomings and engines of cars of a class of S.Tak, in the C220 version of release of 1994 the raised turns of idling (they spontaneously increase to 2000 revolutions per minute) because of defect in a drive of butterfly valves are noted. This shortcoming can be eliminated with a way of change of a fixing pad of a cable. In the C230 version to a turbokompressor there are separate cases of failures of the compressor because of weakening of fastening of an air pipe on an exit of the air filter (it is eliminated since November, 1995).
All cars of a class C are characterized by bad dispersal at not heated-up engine therefore until the motor will not get warm to working temperature, the pedal of an accelerator is necessary for pressing carefully, carefully dosing out supply of gas mixture. In C220D C200D/versions of release of 1994 there are failures in operation of the engine, in particular, during acceleration at average turns (because of problems in the computer (a chain of management of TNVD)). On separate cars the computer of engine management was replaced on a guarantee. In versions 220D/250D of release of 1994 noise of valves and a nagaroobrazovaniye on the final valves, causing capacity loss because of decrease in a compression in cylinders (valves are not closed completely) take place. The problem is eliminated in 1995 with a way of drawing of a chromic covering on cores of valves.
The electric equipment very good and complaints does not cause. The only thing that it is possible to note here, changes of adjustment of external rear-view mirrors when closing doors in cars of 1994 (a class C). In the cars equipped with the conditioner of air, after its switching off glasses, especially in case of strong pollution of the filter immediately mist over.
What to prefer?
The Mercedes car with the 201st body is standing purchase. And it even still more belongs to cars of a new series C.
In the C230 version with a turbo-supercharging: possibility of refusals of a turbokompressor because of weakening of fastening of an air pipe on an exit of the air filter.
In all cars of a class C: bad dispersal at not heated-up engine.
In C200D/versions of Ñ220D 1994 g: failures in work, in particular, during acceleration at average turns of the engine (because of problems in a chain of management of TNVD).
In C220D/versions of Ñ250D 1994 g: noise of valves, formation of a deposit on final valves.
In cars of 1994-1995: trudnootpuskayemy (especially in a cold season) the lever of the parking brake.
Progressing deformation of a plastic frame of external rear-view mirrors.
Pocherneniye of a covering of the sun-protection peak, amplifying eventually (especially in cars with the hatch in a roof), deformation of a plastic frame of a ware box after 6 years of operation.
In some cars of release of 1994: aerodynamic noise because of bad adjustment of locks of forward doors.
In release cars till May, 1995: fragility of a hook clamp of a cowl.
In cars of 1994-1996: a scratch and a gnash when lifting glasses of forward doors.
Bad adjustment of a sled of the hatch in a roof, possibility of emergence of scratches in operating time of a drive of the hatch, deformation (swelling) of the top part of plastic in the basis of forward lateral glasses after 1–2 years of operation.
In cars of release of 1994 with the air conditioner: a zapotevaniye of glasses after conditioner switching off.
