Many of us are wandering in the wilderness of the 11 states where Tucson PHEV's are sold, trying to find a particular trim, color, etc. There is some question about the timeliness and accuracy of the inventory on the HyundaiUSA web site. SeattleGrey took the approach of creating a list of Hyundai dealers in target areas and contacting them directly to let them know what they were looking for. That got me to thinking, and I was able to find two web sites that list all Hyundai dealers in the country and by state.
