YEP!!
that was the obvious hint I was hinting at. If you noticed the 24ct gold then you would know the F1 was the only car to have it do to extreme heat
while I give you props for the 911 (996 GT3), notice the intake/exhaust values on the sides; boxster engine
I must smack you upside the head for whatever logic you used in thinking that was a Gallardo
second I'm guessing is an F40. Others I'm not sure
second is an F40
the first may not be obvious just looking at the desing if you are not familiar with it, but there is one very distinctive clue that will give it away if you can spot it.......and even know why its that distinctiive.
the third is hard, but once you know, it does become obvious as theres kind of a big red flag right there if you pick up on it
