Personal opinion:
Picked up my wife's new Bolt Premiere with two-tone leather heated seats on Monday in Northern Virginia. We both find the seats quite comfortable and plenty wide enough. We're both at healthy weights for our age & height.
My wife & I picked up our white Premiere from Ted Britt last night. They'd only had it off the truck for about 3 hours. The salesman said he hasn't really even had a chance to drive them, they're spoken for as soon as they come in.
I called 3 in Northern Virginia. Two said they had no idea when Bolts would be coming in and no mechanism for me to reserve one. Only Ted Britt had Bolts on the way for purchase. YMMV.
I don't think they have any in stock, but Ted Britt in Sterling, VA has some coming in. I'm expecting a White premiere next week from them. They told me they're one of (if not the) highest volume Volt dealers in the mid-Atlantic, and so they're getting them earlier than other dealerships.
