need some pointers before i plunge.. i'm pretty much set in getting a used 2014 F20, the condition is good for a 4 year car and it is only about 40k km in terms of mileage. is there anything in particular that i need to check that may not be visible on exterior inspection for instance, checking the engine parts for leaking or something. any "known" problems of the F20 that i need to take note of? don't want to be buying a car and then spending half of its price fixing it before being able to drive it. Thanks!
