We say The GranCabrio is a fantastic machine, and much cheaper than its closest rivals.Performance The 450bhp 4.7-litre V8 does fail to reach its full potential in such a heavy car – but that doesn’t mean it’s not superb. It’s quick, without rattling your organs, and is extremely smooth, with a soundtrack made all the more awesome by the topless nature of it.Emissions 354g/km is predictably awful, as is 18.5mpg on a combined cycle with the GranCabrio.Driving Taking the GranCabrio‘s heft of it into account, it’s quite nimble, and at high speeds it’s extremely comfortable. However at lower speeds you’ll feel every lump and bump – not a good match for the UK roads.Feel Despite being a soft-top, wind noise isn’t an issue, and the same goes for road noise. The GranCabrio’s engine sounds fantastic when throttled, and when cruising or at lower speeds it remains hushed.Space The GranCabrio is more practical than its rivals, even if the boot is very small 173 litres). There’s enough head and leg room in the front and rear for most people, which isn’t surprising given the size.Equipment Climate control, alloy wheels, leather upholstery and satellite navigation are standard. The extras list oozes luxury – wooden rimmed steering wheel, for example.Price It’s expensive to buy and run but it’s sold alongside equally expensive rivals. GranCabrio resale values are very good.Quality This is where the GranCabrio falls short of a lot of its rivals. A lot of great quality materials are complemented by some really cheap ones.Safety Six airbags, stability control and traction control, along with a host other electronic safety aids come as standard on the drop-top Maserati.Pros Looks fantastic, amazing driving experience, spacious cabin, good standard safety kit.Cons High running costs, some questionable materials.Alternatives Ferrari California, Aston Martin DBS Volante.
