Hello and welcome Tim
I'm not aware of any major concerns with the variant you have bought. With all Renault's, electrics can be cause for concern as they tend to be a weak point! Also, expect high maintenance bills for the 3.0 engine as there's no room under the hood which equates to longer hours for labour
Has the cambelt been done yet? If not that's a large bill as it's an engine out job IIRC
Hope I haven't put you off too much

Enjoy the car, they are a wonderfully comfortable machine with the power there if you need it
