the car was bought last year and I have repaired lots of parts of the car to get RWC, like 4 brand new tyres, new brake, and others .
However, I just used the car for about two month for working.
Now there is a problem with car that it may break down on the road sometimes, but can start again after 20 secds. There may be something wrong with the cable or oilway, but I dont have time to repair it, and I dont really care with the problem because it works pretty well for short distance like shopping.
If you really wanna fix the problem after you bought it, it may cost you hundreds or 1 thousand. BTW,you need to obtain a RWC yourself, this may not be a problem in a garage test, or may be, I am not quite sure.
