I'm not familiar with autofair, but I've been to autoserv tilton, and I will never go back.
Sales person I spoke to was a jerk, and so was the finance manager. even after I told them I wanted to test drive a couple options before making a decision and immediately tried selling me on things I told them I was NOT interested in. It is the only dealership I have been to where they wanted me to talk to the finance manager before I even settled on a vehicle.
I walked out, and went to Irwin Motors in Laconia. Irwins was awesome, no pressure, they listened and worked with me. Took few a different test drives over a couple weeks before I found what I needed. The sales guy was great, and called me as he got new vehicles in that he wanted me to test drive. It was the exact opposite of Autoserv
