Oh yes! You are right.
Infact the difference between the 365BB and the 512BB is that the first have the front bumper (the anterior body) more small without the "spoiler" and for this at high speeds the 365BB have less stability than the 512BB that have the anterior body with the "spoiler".
However, my next dream is buy a F40; and if the prices will remain the same of now from 5 - 10 years, i will buy it.
Perhaps also if it's price will go up... now i don't know.
I had the opportunity to try as a passenger a F40 of a friend and i had sensations crazy!
It's like a race car!...
