I actually flew to Chicago to drive this car for work in late Sept.I have to admit the APGS is not necessary but it is a fun toy to play around with.This car is about having everything other cars have plus more.Why do we have a 8 spd because 2 weeks earlier Mercedes announced their new 7 spd so we went one up on them.Do you need an Executive Class Seating in the back with a reclining seat with adjustable ottoman,flip down 9 inch DVD screen and a remote operated shiatsu massager?No way but people want to say they have it.This car is for the guy who has ALL the toys.Why do some people have 700hp,because their buddy had 600hp.It's not really the car I like,I'd go with the GS450h.A Hybrid that does 0-60 in about 5.2 and has more luxury than I would ever need.Oh yea,when you get some experience with the APGS it takes about 10 seconds to set it up and go and it will also back in a regular spot at the Grocery Store.
