Skyfall really left me baffled with its Aston Martin. Bond seems to "remember" it and we are meant to think that he's driven it but he can't be the same guy who drove it in the 60s. Or should we just think that it was Bond's first time to drive some 50-year-old car and it happens to be exactly like the one in the other Bond universe? I think Craig's Bond films as a different timeline than the older ones as it was the first reboot, but this just doesn't make sense. It probably shouldn't either, but still.

Craig's Bond got the Aston Martin on his first mission as a double zero in the film "Casino Royale". I would say that is why he remembers it fondly. Skyfall is presented as taking place years after "CR" and "QoS", so I felt that Bond had equipped it with gadgets and must have used it several times on missions between "QoS" and Skyfall.
