Go with the 4.8is, you'll love it, make sure to have PPI done (Pre Purchase Inspection if there is something like that in Europe) before buying it, I am glad i did since it did show some that some suspension bits were worn out and the seller fixed that.

Make sure they have all the service history documents so you know how the vehicle was maintained.

JCL listed most of the stuff you should be looking out for and which might have to be replaced.
