Hello, great spot, but i'm afraid i have to disapoint you because i think it's a replica.
First,the rideheight is too high, for example the rear wheel arches should cover the top of the rims, second the exhaust looks different, it's too long and at the front of the exhaust there should be a little bit of bodywork covering the exhaust where it come's out the bodywork. Now the D-type is/was a racecar and race cars often have their difference's, depending upon where they had to race and often the team made their own adjustment's thinking they could (or try to) do better than the factory and so on. also these jaguar replica's or continuation cars are made so well it's difficult to tell from a picture. anyway still great spot, i never saw a real one or a replica on the street. a big like from me.
