You could do a bracket just for bond cars, problem is that some of the movies have the car as a main plot point while others it's basically a nothing burger.
Also, some people are so biased by what they think they are supposed to answer that the DB5 has a huge advantage going in. And what do you do with non bond cars that were featured, such as the Mach 1 Mustang in DAF that can drive on 2 wheels through a narrow alley and somehow switch halfway through? Are those bond cars too? The motorcycle in TND?
Oh, and I preemptively move that the Vanquish from DAD not be considered as I refuse to include that movie as a Bond movie. That was an attempt to sabotage the series.
