:goodpost and :iagree
I think this is your best bet, or have a look at the decal makers links here to see if you can order some for the lambo.
I have heard of AUTOart sending out replacement parts for their cars (aerials etc) but I don't know how you'd go with a decal.
Best of luck with it though and please keep us informed of your experience with AUTOart. It'd be good to know how they respond after the recent Exoto experiences.
