I was invited to the UK launch of the Maserati GranCabrio, the convertible version of the GranTurismo, the car I am lucky enough to drive. Recently launched at Frankfurt, the one extant example is now on a world tour in advance of the the model going on sale next April. It is, quite simply stunning - an object of intense desire. I would go so far as to say Modena never produced a more beautiful car. Sadly, I will never own one.

The main problem persuading Mrs P. to allow me to buy Vittoria was her 260 litres of luggage space. When we go on our Summer holidays, Mrs P. easily needs all that and I must settle for a small grab bag behind me. The GranCabrio is a full four seater but the space for the retracted soft top consumes 90 litres of the GranTurismo's luggage space. It has barely capacity for overnight luggage for two, let alone a fortnight's luggage for four. This is a design fault. "Claudia", my AMG Mercedes convertible lost no boot space to the soft-top when it was raised. Once the bags were safely at our holiday hotel the roof could be lowered. I cannot imagine why the undoubted design geniuses at Pininfarina did not copy that.

Still, the GranCabrio is an awesome car and immensely beautiful. I hope it sells well so that the world can be enriched by its undoubted charms. I will smile every time I see one, even it it's not for me. Here is a short video of the world's one copy being unveiled at the Belfry last night.
