Thanks guys,
I'll be honest, not a car I'd really looked at before but now walking around it, it is a nice looking car, as are a lot of the Lexus range. It had to go back to have some back order trim replaced and they leant me a NX, again a nice car.
I have looked at some US sites to get more info, I work in engineering so I like to understand how things work, especially the handling in sport+ mode and it's nice to share info on tyres and stuff.
And I need to not fixate so much on economy, an enthusiastic 30 mile drive on clear B roads has dropped the average mpg to 27, obviously a car that needs to be enjoyed rather than driven for economy!
All in all I'm pleased I chose the car, I've got a few long distance trips coming up and I'm looking forward to see what it's like.
And hats off to Lexus dealerships, excellent service + given me a comprehensive price list for servicing and common parts/fitting, my last luxury car was a Honda Legend and I was impressed by their service but I think Lexus beat them.
