I'm no Ferrari knowing man either,but when I first saw it,I thought it's a Testarossa,but then I knew it's wrong as it looks older then the late 80ies car. Later I noticed the 512BB logo on rear,googled it and now I know what's that.
Yeah I've seen quite a few of those Maserati GTs around here
As far the number plate goes it can cost lots depending on the lettering and availability then you just need to fill out a few forms to transfer new plate to your vehicle
I will try and get a picture of my companies CEO new car, he got delivered last week, a Ferrari California, with 5 miles on the clock. He had a Audi R8 before that with Lambo Engine.
Just the way it is in the UK at least, Plates can fetch a lot more than that one, 2 digit (one letter, one number) plates are usually well in excess of a £100k like this one . Some plates even make into the millions.
I guess people see them as an investment/status symbol.
On the other end of the scale, you can get basic ones based on modern plates from £250.
I've been seeing these cars daily. http://www.teslamotors.com/
Not so much the roadster. I've seen one or two, but I see I dunno at least twelve of these a week going back and forth to work.
