Does a dealership have to disclose if car was in flood waters

I believe that is required by law but if it has been through auctions it may gat lost. Hopefully it was reported to Carfax by the insurance company.

Reputable dealers value their reputation and would never knowingly sell a flood car but CraaaZy Ernie's Used Car Palace and Massage Parlor would sell you one is a NY minute.

Check the Carfax or Autocheck-or both.If the car has supposedly gone from state to state especially Indiana and NJ.Someone may have "washed" the title. Not every state carrys over a "brand"(Flood,theft recovery,rebuilt salvage) that a previous state marked(branded) on the front of the title. If it is an older car,it may not have gone through insurance at all,and was never branded. Not every state brands titles The dealer you got it from may also be unaware
