What should I look for in a used Lexus GS saloon?
Provided the person selling the car has bitten the bullet and had it serviced, you shouldn't have too much to worry about. Anything less than a top three position in customer satisfaction surveys is regarded as failure within Lexus, and the Japanese company's reliability record is second to none.
That doesn't mean you just smile and hand the cheque over, because there are still problems to look out for. There have been reports of suspension faults, for instance, so listen carefully for knocking or clonking noises. If the car has clocked up over 60,000 miles make sure that the cambelt has been replaced.
Ask for proof of when the brake pads were replaced, too, as the GS tends to get through them rather quickly. Also check that the anti-lock brake warning light comes on with the ignition and goes out afterwards.
