someone give me some advise

just bought a car from a guy on hear claims to be a cop, the car is titled in his name and everything he told be all vins match up and its legit as can be. buy the car and get home with it notice the vin on dash doesn't match title. the title matches the fire wall and door jam. he tells me they swapped the dash for another civic dash that was black but the first time I asked him he said he bought it that way. after asking him over and over he remembers the changed the dash???? idk what to do with this car. is this going to be a problem with selling the car or inspecting anything like that????

the guy is telling me it is fine and not a big deal idk what to do
