how to tell a genuine EB XR6

[DEVL-XR]

i was out in town driving around tonight and i met 4 e-series boys, 2 cars - 4 people. there not on here but i told them about the club and the forums.

anyway we got talking and they seemed to regonize my car. then there trying to tell me that they knew the guy who previously owned my car and tryed to tell me they did a manual conversation in it and put the tickford motor in.

so what im asking is there any way to tell if my car is genuine or a mock up. do genuine eb xr6's have anything to notice on the ID plate in the engine bay?

i beleive these guys are trying to pull my leg because if its a mock up then they've done:
tickford engine
tickford suspension
xr6 door trims and seats
sports cluster
rear xr6 boot garnish with xr6 sticker and falcon s badge
side red 4.0 badge
xr6/s wheels
lsd
the car is also marine blue, i think this colour only came out on 's' and xr didnt it?

etc etc...

when i got the car it looked exactly the same as the photo of the EB XR6 on the fpv website.

so are these guys pulling my leg or not? i beleive they are..

cheers
