I can't speak for the carseat thing (hopefully that's a LONG way off for me) but even with a passenger on the same side I often found it to be PITA getting out with a big truck parked next to you. Couldn't imagine trying to wrangle a child seat out without smacking one of the doors with my elbow into the car next to me. Not saying it couldn't be done but just saying it might suck vs some of the alternatives.
Just my 2 cents.
Hell I'd expect a good discount with the 3rd transmission being in the car![]()
