Anyone who doesn’t like cars must find it astonishing that anyone would want to stare at a picture of something that resembles a pile of cardboard boxes on four wheels.

But I’m sure I’m not alone in finding spy pics fascinating.

Sometimes you can’t really see the car, or it may even be a mule with the body of a car that’s been on sale for years, but throw in a shady backstreet or a camera-shy engineer and it’s the perfect mix.

Take the Maserati Spyder for example, it is not what you can see but what you can’t that draws you in.

It is clear that the front and rear of the car will be pretty much the same as the GranTurismo, but what can’t be seen is the roof.
