It may be my imagination, but I don't see that the OP is looking to sue anyone here. Just asked what they should do? It appears that someone made a mistake. If the Title says 2010, then call your local Motor Vehicle Registry office or the office that issues the Titles. They have a record of the vehicle's ID number (VIN). They will be able to tell by that what year the car really is. IF you find out the vehicle is indeed a 2010, then you go back to the dealer telling them what you found out and show them a "copy" of the Title to prove it. At that point, the gripe is between you and the dealer and you may have some legal recourse. But, if it turns out to be a 2011 vehicle, then the Registry made a mistake and they'll need to issue you a new Title. I live in Massachusetts and a car I once bought had something like 56,000 miles on it when I bought it. When the title showed up, it showed that the car had 156,000 miles on it. Clearly that was the mistake of the Registry. I went to the registry and told them about the mistake. I even had to have a State Trooper check the car to confirm I wasn't lying. They fixed the Title and sent me a new one. Before you spend your money on litigation services, make sure who made the mistake and if it can be fixed. May save you a whole lotta bucks!
