From a video taken by rebels of Bashar al-Assad's garage, I saw some interesting ones in there.
He's got the RR Phantom and an AM DB7.
A couple of Lambos. LM002 and a Diablo.
A couple of Ferraris. F50 and F430
I wouldn't be surprised if he's got a 600 Großer. A proper dictator head of state car to complete the look.
