GMC Acadia vs. Mercedes GL

Moin together, was at the Mi on the IAA to look around for SUV’s with 3 rows of seats….and has to confess that the Mercedes GL with Abtsand has the best processing and the best space, also in the third row, and (more important) behind it. But since March I am diligently collecting information about the GMC Acadia, I have compared now: Loading volume has the Acadia according to paper 1000L more !!!! clearly to be seen on the pictures he also has more space inside. Fuel consumption sc But the acadie would be less than half the cost until it is here!!! That’s why the question to everyone: Who has already experienced with the acadie and can tell me something about quality and workmanship. Even better would be information where you can look at one in D times / test drive. Already in advance; am Ami quality already used, I drive currently 2006 Mustang GT and need now still a family carriage. Would be great if someone could help. So far greeting Andreas
