Sure, an Aston Martin DB5 like the one James Bond drives in "Skyfall" will cost you an arm and a leg, but if you want to drive a car like the movie super-spy, you may not have to shell out big bucks after all.
This was from the era when Britain's top spy was driving German cars. The 7-series sedan in the movie could be driven by remote control it could teargas enemies, shoot missiles, and drop road spikes. It even had a pop-up wire cutter. Your 7-series won't have any of those things but, honestly, you'd probably just hurt yourself.
