I'm picking my EV6 up 3/5 from out of state, about 2.5 hours away. So far, they say they don't even have a part number for the hitch. It's in the accessories list for $540, but they can't tell me if it's 1.25 or 2 (or 2.5) inches or when they'll have it. I'm not going to do another 5 hour round trip to get the hitch from them if it isn't available by 3/5. Anyone have any info on getting a hitch installed so we can get bike racks?
