There are two body styles: the regular five - door model and the larger Tivoli XLV, which features extra boot space thanks to an extended tail section. (autoexpress.co.uk)
The new A5 has 10 litres of extra boot space over the model it replaces, though, at 465 litres that's still 10 litres less than the A4 Saloon on which its based. (autoexpress.co.uk)
Unless the hair / wind / pose interface is a necessity, we'd go for the carbon - roofed coupe, pocket # 5k and think what to do with all the extra boot space (a handy 460 litres compared to 300 for the drop - top with the hood down) on a long trip. (evo.co.uk)
