More than 300 cars were available, including the likely best selling 1.7 CDTi and 1.6-litre Twinport.
Mike Wear, manufacturer and dealer relationships director at Motability, said: 'The new Astra is a major advance on the previous model with huge improvements in styling and driving dynamics. 'Of course, it is entering a highly competitive sector of the market with the new Volkswagen Golf on sale, and the new Ford Focus to come later this year, so it promises to be a very interesting time.'
Tim Bowden, director of supplier management at Bank of Scotland Vehicle Management, said: 'The new car has a refreshing styling that breaks the mould of the previous model, and the drive was dynamic and enjoyable.'
Nigel Trotman, business relationship manager at Whitbread, said: 'It was much better than I had anticipated and I was very impressed, particularly with the new 1.7 CDTi, which was a very responsive engine.'
Fleet consultant Steve Cox said: 'I thought the styling was excellent and it had a very solid, well put-together feel.'
