One of these was thrust upon me as a courtesy car when my Fabia had its rear bumper replaced. I cancelled all driving lessons, a I was not prepared to inflict it on any of my learners, or myself, as the lack of any 'go' would create many really frightening situations. As Steven suggests, good only for those who need to do short slow journeys, in flatter areas.
We had the Corsas with BSM. The 'C' 1.2 was a quick little car, but the 'D', being heavier struggled to pull itself along. Early cars also had higher gearing to 'compensate' for the heavier workload, to try to regain some economy, but that made it worse. With so many BSM instructors complaining, (and some owners I guess) Vauxhall responded by refitting the 'C' lower ratio gearbox. The car was much better, but still significantly slower than the 'C', and now much thirstier. The 1.4 'D' was almost as quick as a 1.2 'C', and almost as economical. Progress. The the heater fans seized. We had about 8 of these around Swindon, all had their heater fan motors replaced within months. (Also afflicts the Grande Punto, at least they are cheap, available on Ebay, and easy to replace.)
