| - 2 - Continued:- following wind at 35 miles per hour, the car tended to fill with exhaust gases but this I believe was due to the continual low speed used and a directly following wind which caused exhaust fumes to encircle the car and when pulling hard in top gear at about 20 miles an hour booming set in although this may have been associated with the Burgess type silencer which was fitted. As far as details were concerned it was refreshing to see that S.U. carburetters were fitted with advantage and it was notable that the engine idled at about 300 to 400 R.P.M., I was pleased to see that S.U. carburetters are being employed so efficiently as there is no doubt that a considerable gain in performance can be obtained as well as complete freedom from excess richness which is often experienced with acceleration pump type carburetters. Another point which was interesting was to note that a Bentley scheme of ignition had been used. The starting from cold was excellent being just a matter of switching on and pressing a button which is a welcome change from 2 - B - 50, which was rather like coaxing the Italian Navy out of the port. Summing up one can say without the least hesitancy that for the purpose for which this car was designed it represents an ideal combination of comfort and performance and is particularly easy to drive and one would think that some exceptionally good averages could be put up with a complete lack of fatigue on both driver and passengers, in fact I am in agreement that this is a car for which one has to make no excuses.
