Our 1 year old daughter's seat is on the passenger side & we put her in through the passenger door, find it easier that way as then adults can get in the back using the club door (when I say adults, obviously I mean 1 at a time!). It's not as easy as a 4 door but definitely easier than our old One (we used to put her in through the hatchback when she was in a rear facing seat.
If the dealer has one in stock to the spec you want, let them think it is to a higher spec than you wanted & they should offer some discount- especially if it's their launch model.
