If you could own any famous car from a movie which would it be?Watch
But my first love is the Quattro from Ashes to Ashes
Close second would be the '68 Mustang from Bullitt.
As an icon the goldfinger DB5 would be cool.
To drive regularly id go for the old gen DBS (late 2000s one with the 6l v12 featured in casino royale)
David Hasselhoff's Knight Rider.
Most famously the DB5, although I think some people are still fond of the Lotus Esprit.
Personally i think the best all round is the DBS as it has a luxurious cockpit, performance capable but chassis for grand touring as well.
The best driving capability car is probably the DB10 which is essentially a body kit on a gen1 vantage but really tuned for stunt driving, but it would require real skill to drive (this was never a production car, only for the movie).
If you want the one with the most funky amount of gadgets & guns popping out all over the place I think mk1 vanquish (very early 2000s) had a lot.
