My love of Bordeaux interiors is well documented. Otherwise, I think it really depends on the model - for me, beige is ok for a tourer, but not for a sports car, where I prefer black or some of the tech cloth GS options. For example, a Stradale with a beige interior would be utterly wrong! I also like the fact that an all black interior will tend to look less dated, whereas something like the second picture looks very dated:
The QP is a newer model, though, so will be a bit longer before the interior starts to age.
Also realise I'm not the typical Maserati owner - I don't like two tone interiors or piping. When I'm in the car I'm listening to the engine and looking up the road!
