Do Aston Martin cars use jaguar parts?

Considering the fact that both, Jaguar and Aston Martin, were part of Ford's Premier Automotive Group division (Ford sold Aston Martin in March 2007, and is expected to sell Jaguar as well sometimes in the fourth quarter of 2007), there's a very high probability that Aston Martin uses Jaguar parts and also the other way around. It is also possible that Aston Martin, as well as Jaguar, are using Ford parts.
