I ended up buying in MA about 8 months later. I got the same spec'd out truck as the 23 but it's a 24 and got it last August. I drove about 3 hours to get it so up and back same day. Trade was really good and new car price was decent for the time period. Right now the incentives are even better from GM.
Laura definitely has some good prices, but for my specific case, given my age and other things, it wasn't in the cards for me to fly there and drive home. I did want to trade if possible because of the steep MA tax. The round trip shipping costs were approaching $3000 if I remember correctly and it may or may not go smooth based on some of the reviews I read. In the end I just didn't want to deal with some of the variables but I'm sure others have done it successfully. Good luck on your venture.
