Hello, AlexGin, you wrote: AG> Acquires it our daughter, which 20 years. It at it the first machine. Very much wants to acquire a car while it does not have family. AG> she wants to take the credit and to acquire the given device. At all I do not know what to tell to it in this occasion Purely my subjective judgement. In my opinion there are two types of repair: 1. Repair of an old detail 2. Changeover of a detail on new Many nodes of the car can be repaired possessing knowledge and tools. By analogy to the computer if the videocard broke, it is possible to buy new and to replace, and it is possible the burned down chips. It for the general understanding how much different preparation level is necessary. Independent repair of an old detail is the cheapest, but it will be inaccessible to your daughter. There is a changeover, and here it is expensive. I do not know as in other countries, but in Russia the fuel price, whether it be qualitative gasoline or a role diesel engine in comparison with repair does not play. At the old car repair and changeover can strongly exceed remaining expenditure. For this reason within 5 years owners there are new cars get rid of them and buy to itself new. Thus the second owner it yet so is bad, in comparison with that them can be much more. From the moment of purchase of the new car it is possible to lead a large quantity of actions named maintenance service. It is real , but the car as they say will serve faithfully. And it is possible the car, then to sell to any little fool and to buy the new. Because of it I basically against purchase of the unknown person Second-hand. If it is not enough money, it is possible to consider a variant with a new foreign car, that is not the Russian brand which costs above in a rating of favourite cars of taxi drivers. As to gas it is full of articles where it is visually shown, how it destroys the engine. Therefore is not present, the variant on gas for is bad. Not clearly who also that will put there. On such risk owners of commercial transport can go, but it is not necessary to normal people. Plus a gas bag in the car, and with it too not all so is simple. Eventually still depends on the price for a specific type of fuel. In Russia gasoline could cost cheaper much, as well as gas, and its price it practically entirely a policy of the state. Anyhow, but assume I the taxi driver, delivered the gas equipment, the car going for a drive on it for days on end and without being put in the full maintenance service, still bragged as spared for the gas account, and then sold this shit. And everything, it any more not my problem, it now a problem of that idiot that bought it. Thus buying not the new car it is better to prepare for troubles at once. A rule from life, the good car very few people will sell for cheap, and here bad for expensive easily. Whether the answer to a question will expensively cost repair. Car repairs and furthermore car cost can superimpose foreign cars several times. At some happens even so what more cheaply to buy new, than some years to exploit the old. I not the clairvoyant to predict risks was specific this car, but from the point of view the risk of management needs to be considered it. Last, we assume the old car has been bought, that is everything, there is no place to disappear already, only if again to sell. At once drag it on diagnostics with the lift first of all checking systems responsible for safety, that is brake system, a running gear and so on. Not so it is terrible, if the car somewhere decays, it is possible to be prepared in advance on this case learning wrecker numbers as if there will be a failure for the speed.
