Is there anything we can do if a dealership has harassed us by selling a damaged truck?

My husband bought a truck March 5, 2013. We immediately insured the truck with full coverage insurance. The bank called my husband the next day and said they would get his payment book in the mail to him. The car dealership called almost every day for 6 weeks wanting the truck back, saying the finance company decided not to finance it. On April 23, 2013 I returned the truck to the dealership. The next day someone bought this truck, didn't even make it home in it and found out the truck had been through Hurricane Sandy and the gas tank was full of sea sand. Other vehicles they sold were all damaged in one way or another. One was cut half into and put back together and sold by them. July 23, 2013 my husband bought a truck from a different dealership. He got financed through the exact same bank that he was supposedly denied credit from on the 1st truck and with no problem at all this time. It seems this bank ran my husband’s credit which checked out fine, but when they ran a report on the 1st truck it didn't check out (because of Hurricane Sandy damage). For 6 weeks these people harassed us to the point my husband almost had another heart attack, and they totally wrecked both our nerves. Is there anything we can do? They're jumping around from town to town locally selling these vehicles. One week in one town and then gone, and a week in another. They have 15 complaints with the better business bureau. I'm not sure what to list this under, so I went with personal injury.
