How to ride without problems

Most customers vehicles like one - just go, navedyvayas to the dealer only to get another TA. To do this, take out loans for new cars, compared to producer prices, are carried out test-drives. The problem is that by selecting the appropriate criteria for the car - the level of integration, design, engine power, control - resulting in a person receives or is not quite what I wanted, or not at all, and sometimes even forced to go to court, remaining for a long time without a car altogether. There are many problems, the most common - the unqualified service. On a new car on fire «Check Engine», car went into emergency mode, goes badly, consuming much fuel. Diagnostic equipment dealers shows nothing. In the service center put out the light bulb, three kilometers «Check Engine» lights up again. The indignant customer claims the answer is simple: "There are recommendations for repair, an engine tester, if it shows nothing, we can not help you." Sue? Long and troublesome. What is the output? I propose to publish a list of models showing a complete set, which during the operation to show their good side, as well as to publish a "black list" of attractive features, but very unreliable car. Of course, based on personal experience.
