trice,
I will post pics of the interior when our family's only photograpic expert recovers from 'flu - she will want to take her time over the problem of the tech fabric because it tends to reflect flash so badly.
The interior is exactly the same as thebimbo's car apart from dark red mats which I thought would 'lift' the appearance. Now that I have the car I'm quite pleased with the tech fabric - Nero, which is really a dark silver, and contrasts well with the black leather.
The Porsche question is very difficult to answer. So much depends on individual preference and the type of driving you do most often. At this stage all I can say is that the Porsche is more of a sports car, and the GranSport more of a GT. If you want a circuit car go for the Porsche, but if you want an intriguing road car with character go for the Maserati.
The Porsche is, to me at least, far too clinical nowadays. Beautifully engineered, famously reliable and safe as houses through difficult corners, it still doesn't talk to you. It drives you, and pays very little attention to what you think, say, or do!
Bear in mind that I live in a part of Scotland which is 60 miles from the nearest proper city, so most of my driving is on quiet country roads or motorways, and the cambiocorsa system is ideal for the job. How it would cope with pure city driving is difficult to judge, but initial impressions with the GranSport are encouraging.
A complex subject - maybe I'll make more sense when I've done a few hundred miles!
