This is just a general question that i have been trying to find the answer to. What is the most expensive car in the world? I have read here and there, an old Bugatti, a Ferrari 250 GTO, the unsold Rolls Royce Silver Ghost that BMW has, I don't care if it sold or not, I want to try and find out the most expensive car, sold, or valued at at one point in time, there ever was / is. The most expensive car now, the most expensive car in all history, the top most expensive cars etc. I haven't had much look in books or the net so I was wondering if anyone here knew.
