Jag engineers "developed" the engine by raiding the parts pin from Ford to cut cost. They DID NOT develope this engine from new parts but rather parts that's including the Ford Taurus. As for the Aston Martin, especially the $325,000 Vangquish, if you read any of the reviews on it, the #1 complain is material used for the interior, door handles and radio from the Miata???, wood or aluminum from Taurus or Lincoln. What do you think the Lincoln is based on, where did the chassis come from, Taurus baby.
