I had the NX first five years ago and it was when I took her in for some recall in 2020 , that when I collected her she was parked next to a used RX for sale with very low miles, and I shouldn't have taken a second look, but there I was having a test drive in it two days later and the rest is history. I loved the NX except for the gear box which had noisy tantrums when you tried to push her a bit. Think they have modified them since. So I did a swap and loved most everything about the RX , it was like stepping into a different world , more space, more comfort and more presence. Solidity and the CVT in the RX was completely different. Mind I had some problems with her that made me feel mistrustful in the end, so I had a brief love affair with a Touareg, and on Wednesday hopefully I'll be back to normal with the RX.
I did set out looking to downsize to the NX but at times it used to feel a bit cramped compared with the RX.
Really like the Blue on your motor, assume it's with Ivory interior. Did you get her from Teeside Lexus? I had my NX from them and they were excellent.
