Unfortunately, he is wrong. E-Four is an option on ALL UX models, even the Takumi spec.
I think it was said earlier in the thread that the AWD option on these is a gimmick. I am a sales exec for Lexus and I will have no issue telling my customers this. It will make the car heavier, more expensive, worse MPG figures and is basically redundant. This is not an off road vehicle.
This also means that you will be able to buy a top spec UX Takumi with a paint option and it will fall under £40,000 as long as you dont spec E-Four...which you don't want to!!
