You know, I might be crazy, but I would rather see Bond driving this car that that Aston Martin Vantage. He is going to South Africa, so Q gives him this completely tricked out bad-
little car the flies along at 200MPH. We expect to see guns flip from behind the headlights of a Aston because, well, we've seen it a zillion times. *yawn* But Bond pulling up in this thing and people chuckling...but then later on we reveal a bazooka behind the grill and a rocket for an engine...the thing can somersault through a house and roll down a mountain and still drive away without a dent...that's Bond!

Exhausted in Die Another Day when Bond requests a "fast car" and gets a 1950's Ford Fairlane.
I'm gonna say that if it is in the film it'll have a very very minor role. The entire Brosnan-era has proved to me that unless a car is there for the enemy to get its

kicked in (and I'm not talking Zao - Jaguar = Ford), the car is going to be one by whomever has the big deal. Die Another Day = all Fords; GE, TND, and TWINE = for the most part all BMWs with a couple exceptions such as the Ferrari and the Aston Martin DB5.
I am somewhat skeptical if Aston Martin (Ford) still has the next deal. I mean yeah, I remember Fisker saying that it would be, but that was back in early 2004 and I haven't heard anything since. With the film being released in late 2006, is this still the case? Suppose it's not and this Fiat surely is in, you might be able to surmise that Bond's next car might be a Ferrari (owned by Fiat). Speculation is fun and yet stupid. Very very stupid.
