Yes, I agree - the infotainment team were clearly locked in different sound proof rooms !
Personally, I see no issue with the CVT - I appreciate the noise that it makes but does not bother me. Having had several diesel cars the noise from the Lexus is an improvement, I've turned off the active noise system already as could not see the point of it. The overall ride seems fine to me - in reality it's better that my current BMW which has 19" rims and M-Sport Suspension.
In terms of comfort, the seats are great and remind me of the quality of seat that you used to get in SAAB many years ago. I also like the lumber support which is normally an option in a BMW.
The 49 MPG is 'after start' and was based on my commute this morning. I'll have to check out the difference between after refuel and after reset so thanks for pointing that out.
