I test drove several SUV's and found the NX ride was much like other German alternatives, but firmer than the Freelander I drove. This was before the Discovery Sport was available. The Freelander had a lot of body roll on corners though which the NX does not have. I suppose it's all a balance, and getting that balance right is not easy. i do think Lexus have got it almost spot on, but everyone views it differently. If I was being really picky I would have liked an option to have some sort of damper control to switch to softer or firmer ride, like in BMW's Variable Damper Control (VDR). BMW's without VDR are very firm in my opinion. As for seats, without doubt the ones in the NX are far better than all the other SUV's I tried, only Volvo can match them. Lastly, I have never found the NX under powered. Only once in 18 months of driving when overtaking a slow lorry on a steep hill did the engine wine a bit, but it was not too bad and when I slipped it into Sport mode it was fine. For all normal driving the car is superb and quiet, unlike diesels. It is also a nice place to be, unlike some other interiors which have far too much cheap looking plastic etc. It is by far the best car I have ever owned. Ohh and it never let's you down, on the reliability front it is simply the best!
