Not sure whether my problem is similar to the one described by Barry.
Essentially for the last couple of months the car has felt unsafe to drive at high speeds in a straight line. Frequently it will lurch to the right for no apparent reason. The car has never suffered from torque steer but now it seems to at around 40 - 60 MPH when accelerating hard, again it moves to the right. I wonder if anybody knows an expert who would look at the car and repair it for me without taking the shirt of my back!!
