At present there's (to my knowledge) only 1 Diablo GT in the Netherlands.

Car (#44/80) is being offered for sale for quite some time now, but the owner seems to be living in another world, asking 450.000 Euro's.
Car is presented by seller as a Diablo GTR (sure, # 44 from a series of 30 - I rest my case...)
