Took the car for an expensive engineers survey today with the AA (equivalent of US AAA). I will have the written report tommorow but verbally the engineer confirmed that there are many problems. I reckon that the steering problems could be specific to Right Hand Drive versions, judging by the very unusual layout pointed out to me today. Anyone in the RHD world care to comment?
