I also just bought from Dobles in NH. Nice guys. I worked with Mark and Peter. Mark pointed me towards a nice open construction area near the airport and told me to go "have fun."
I also worked with Al P. at Hummer of Norwood, MA, he was very nice too. But, I ended up buying at Dobles in NH. Dobles was very accomodating.
Btw, I aslo signed up for announcements via hummer.com and I have received 2-3 emails from them. Mostly announcing availability, new commercials, etc.
