I’m pretty sure motability would go bonkers if you go that. Early hand backs can be done when a car is no longer suitable for your needs. If you hand it back then order the same car…..
Massage seat could be added via a seat cover I’ve had them in the past sure I get the 360 camera but it’s not the difference between being able to drive the car or not.
I’m not saying don’t ask but what I suspect will be the answer. Good luck either way
