I am generally not a big fan of the 599. I consider it quite big and the shape itself looks a bit bloated (I hope I am not offending anyone here).
I asked once a well-known Ferrari designer about these facts and he replied that packaging is a major headache these days for designers. They don't seem to be as free as they were in the past to prioritise form over function.
Also, given the size of the car, I don't think red is the colour that suits the 599 best. I tend to like the darker metallic ones. I don't know the colour codes, but I am referring to dark grey and titanium. Black is also nice.
Having said that, a friend in Switzerland asked me last Summer to help him find a 599. After monitoring the market for a while, I came across a immaculate 2007, 2-owner, dark metallic grey with black interior unit with 27.000 kms. An inspection by a Ferrari dealer showed very low usage of both the brakes (carbon) and clutch, and they confirmed it was absolutely flawless, to the point they were not able to find anything to be done, besides the standard service, which was due.
My friend paid barely above CHF 100K. He was a happy camper!
As a confirmation of my earlier statements about size, I kept the car in my garage for a few weeks, and it really looked big compared to my other cars. The size comparison with the Maranello was quite remarkable.
