I'm also considering a 450h+ and wondered if anyone had compared ride quality between f-sport and other versions? I have tried a standard version and i must admit that the ride and noise wasn't quite as good as I had expected (my LR DIscovery Sport PHEV is better - although I was able to specify that with 18inch wheels (with standard tyres rather than the 20 inch run-flats) - I did a back to back test on the same test run.
I’m hoping to have another try to check again - I really like a lot of the features on the NX and the EV range is ideal for my journey pattern - so I’m hoping to convince myself to order one. Otherwise, I may wait and see what the new RX is like.
