The Vanquish used in "Die Another Day" marked Bond's return in 2002 to the Aston Martin brand after several films in which he drove cars from, oddly enough, Germany's BMW.
When new, a Vanquish sold for around $230,000. That was, of course, without the Q option package which included an "adaptive camaflouge" system that, in the movie, failed to work. (Finicky English cars, you know.) While it's still not exactly cheap, a used one can be had today for $85,000 -- a relatively modest price in ultra-luxury terms.
