I was very pleased with the general behaviour and performance of this car on the run I had last week. The servo squeaks slightly and the brake pedal did not always return to the stop, otherwise the brakes were exceedingly powerful and progressive. The slight servo shudder previously experienced seems to be gradually disappearing. The tyres still squeal quite badly.

The propellor shaft period, which at one time was scarcely detectable, is now gradually getting obtrusive and there is a certain roughness at maximum engine revs.

80 m.p.h. seems to be about the top speed. The steering with the small tyres is excellent.
