Hello, acknowledgment invites. Check car home becomes independent as tripartite car detects orgnaization, what we basically do is two handcart before tripartite is bought, detect, still understand somewhat relatively to this problem so.
Below the question that I answer you from the professional point of view of my individual.
Be in commonly western developed country, of two handcart trade the quantity exceeds new car to trade far quantity. This shows people more it is to choose two handcart, because two handcart have sexual price to compare,be tall, devalue by rate, maintenance petty gain, spend similar fund to be able to buy the car of bypass the immediate leadership. So those who which buy two handcart to be bought one year after all is better? Before saying this problem, have to consider new car devalue for rate. Take no account of the rare model of an unexpected winner first, we serve as an analysis with the popular model of the mainstream on the market. 
Stride with the masses vacate citing child, general new car the first year devalue rate be in probably 15% , that is to say car attention is to devalue one purchases the pattern with duty and similar insurance premium. Devalue the 2nd year in 10% , devalue every year to the 5th year all the time later rate it is almost between 5%~10% . After arriving the 5th year commonly almost car can devalue half left and right sides, for instance at the outset the car of 200 thousand, nowadays after 5 years probably the price is controlled in 100 thousand money, of course this is a cursory consideration, actually car condition mixes the basis different price still meets area somewhat deviation, secondhand after all the car is belonged to nonstandard commodity, so specific clinch a deal valence is met the difference is bigger. 
But the principle that referenced home car suggests to discard as useless, a car from at the beginning of designing, be opposite his service life is 15 years at least, 600 thousand kilometer. Because car arrives 15 years,still not be here or the quality operating mode of the car after 600 thousand kilometer drops cannot the degree of start off travel, mainer reason still depends on the national promotion to environmental protection standard, span of 15 years meets those who bring about car not to accord with instantly discharge a standard, so ability can suggest to discard as useless. Everybody also knows, normally travel course of development of a year is in car left and right sides of 20 thousand kilometers, with the design of 600 thousand kilometer life is calculated, car is almost OK travel 30 years. 
But according to devalue the word 6~7 for rate year the new car price that two handcart are less than a half at wanting only almost for new car relatively, and still discharged purchase duty. Calculate come down sexual price is compared also is taller, so my individual thinks 6~7 year two handcart still are worth to buy, secondhand of course car vehicle besides differ in thousands ways, a lot of people know the dominant position of two handcart, but because concern is secondhand car water is deeper not dare easily proceed with. 
My individual also suggests, if yourself does not know two handcart, search professional personage as far as possible, or beside you special the friend that knows a car. If you do not have such friend to also can be searched really similar home of our check car such tripartite car detects the orgnaization helps you be in before buying a car guard a pass, cite a case. We help guard a pass a car collects fees control in hundreds of money commonly, if car condition is bad, you can abandon buying seek new car source. If we also meet the word of car condition OK,all sorts of volume problems that exist car and car later period need the place that reorganize and outfit maintains to tell you completely, include the cost that reorganize and outfit maintains. The practical car that at the same time union detects besides, return meeting ground car condition offers a referenced price to you, make you intimate tell the other so. The biggest gain is the flaw that realized car condition and car existence completely when you and problem hind, you are mixed more easily sell the home to undertake argy-bargy, the cost that cuts valence province to come down commonly is charge of this bit of service normally is very severalfold even ten times above. 
Above is a bit opinion of my individual, the hope can help you. If you have any two handcart pertinent question is OK illicit letter me. I use up me to be able to help you solve certainly.
