X446 X441 We had an opportunity of trying several 20 HP. cars while we were at the recent Motor Show. Two of the most interesting being - the 20 HP. Lanchester and the 20 HP. Sunbeam. From a purchasers point of view, we would say that were these two cars the same price, we would infinitely prefer the 20 HP. Sunbeam Car from a performance point of view, so that the latter can be considered a very excellent proposition at a chassis price of less than £800. We were able to drive both these cars during the demonstration run. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
