There is a difference of opinion with regard to the ride on this car. The general position is as follows, when the car was passed to me for running, the ride was not good and compared unfavourably with other Wraiths then in existence. Eventually after changing the springs and alterations to the damping, it was considered comparable with other Wraiths and in particular with 26.G.V1. the 15,000 miles car which was considered the best all round compromise.
At the time of the announcement it was used extensively for demonstration purposes and the ride was favourably commented upon.
