Road test※
The test car was the sports model with aluminium pistons, double valve springs, higher gear ratios and a lighter body. The car was considered——to run pleasantly and do around 60 mph in top gear. When supplied for export the radiator is given a fan. There were complaints about accessibility for servicing and minor repairs. The engine was thought to be, unusually smooth for a two-bearing product even at high speed. The steering wheel shook on rough roads otherwise controls were smooth and even. A final comment was "at the price one cannot fairly grumble at three speeds".
