I changed because I no longer needed the bigger car. Also the RX was getting old and I wanted a newer, more up to date model. They are very different cars. RX... + More space + More cosseting. Excellent seats + Effortless performance + Quiet, unless you thrash it + Good visibility + excellent reliability - aging design (mine was a 2009 model) - frustrating infotainment system - poor lights (mine was the SE-I) - collected far too many car park dings - unexpectedly, too many rattles (mainly from rear seats, but not only) NX... + smaller, but plenty big enough + Still love the design, especially the front with the triple LED headlamps, which are very good + Harsher ride, but still very comfortable, even in the F sport + More up to date tech + Panoramic roof (extra) + Excellent seats (mine is the F Sport) + Utterly reliable + Excellent build quality + Cheaper to run, obviously + Easier to park - frustrating and outdated infotainment system - noisy and unrefined when pressed - under powered (relatively speaking) Up front, the NX feels cosier, still with plenty of space. The RX felt more airy, but to be fair, this may have been because of a very light interior colour scheme. The seats keep you in place better than they do in the RX if you are of a relatively slim build, especially around roundabouts. Some people find the ride too harsh... I don't. To me it's just right and helps the car maintain some composure around bends. Room at the back is very good for two, but is only acceptable for 3 on short journeys. 2 six footers can sit behind one another without problem, and we haven't found the pan roof to be an issue. The car is definitely narrower, which can be a problem if you need to fit children seats/boosters, but is a bonus on narrow roads and when parking. Boot is of course smaller and is not as deep as the competition because of the batteries, but is certainly usable and big enough. You don't have to compromise as in the CT or UX. Does this help?
