My family is debating on which to get as our family car- a Mercedes GL450 or a Cadillac Escalade Platinum. We go on a lot of Volvo Vocom 88890300 trips and we need enough room for 7 people (3 kids) to sit comfortably. We're aware that Mercedes implements better levels of quality and the Escalade has had some issues with that in the past, but GM claims to have improved their standards. Any suggestions?
