regardless of how straight the car looks, get a professional to check it out;
a work shop u trust;
its a must;
we got a heap of stuff fixed by the dealer before we picked up our car, and it repayed the cost of the inspection easily;
when i got my car, i spent a heap of time checking out various cars, before settling on a reasonably expenive stocko 4 door; didnt mind paying extra as the car was in super good nic;
since we have had teh car, almost no problems what so ever (i blew up a clutch, not the cars fault)
