Especially when they actually have a third row of seats, technically making it a 7 seater. The quickest MPV perhaps?

The third row is an option, and for children only.
The Model X can seat 7 adults.

Yea I appreciate that, I saw them at a car show, there were two averaged sized adults sitting in them at the time, they are bigger than you think and the footwell is quite deep as there's no exhaust system taking up space beneath the car.
