Congratulations on your purchase, sounds a fine car especially after all the hassle you've had. That pearlescent white is a lovely colour. Quite a shift from a RSQ3.
When we were looking, most ads I would see had inaccurate descriptions and that was from Lexus dealers.
We've had ours for a few weeks now, there are a lot of parallels to our story. We started looking at top spec nx300h's, sat in a few at the big car supermarket type places but never drove one. I preferred the look of the nx350h but didn't want to stretch the budget that far.
Anyway, been keeping an eye on late high spec 300h's and lower end of the 350h's. Ours turned up at an Audi dealer of all places! The previous owners had part-x'ed it for a etron SUV. The description was sparse but I could see it was a premium plus model with the memory seats. It was priced well (incorrectly even?!) I thought and in Green which we really liked. Left a message with them awaiting callback but later that day saw the listing had been taken down and no one had called, assumed we had missed it. Rang them again and they said it had been reserved by another dealer but they are happy showing it to us and rather sell to us. And here we are.. I could only get £590 off the asking price!!
You'll like it, it's a nice car and full of tech. I'd have loved the ML but just couldn't justify it. Does yours have the camera rear view mirror? That maybe a Takumi thing only.
