Just did a 1:1 - product specialist was really knowledgeable - she told me that someone put together comparison charts for literally every EV available in NA and internally to compare against other cars within GM including ICE vehicles. Very thorough. Also, I learned that the cargo space with the 2nd row down in 26.2 cubic feet (the website was only listing the 57 cubic feet max cargo space, so that's very attractive. My ID4 has 30.1 cubic feet behind the second row, so I wanted to have something that would be within 4-5 cubic feet of cargo space, so this fits. Also my Prius (which this would replace) has 21 cubic feet, so as long as it's bigger is really the only condition haha (which is why I didn't want the Bolt EUV which has I think 19.
Edit: She also said that they believes they will use a reservation system just like the Silverado and Blazer but not sure when it will be announced. I think the only time anything was mentioned about there not being a reservation system was some YouTube blogger who mentioned it but no one else has confirmed that.
