Megane rs Monaco gp

Hello everyone, I'm new to the forum and im looking for some infos.

I'm about to purchase a Megane rs 250 Monaco gp. I know they never been imported to the uk but this one seems genuine. Check with Dvla and its register as the only Megane rs Monaco gp in the uk . But the specs are different that the oz model. I'm confused haha any infos or help would be much appreciated.

Thanks

Anthony
