Help... Vin #'s dont match

Ok, Im the OP

I did buy it as a numbers matching car.. I have 9k into it as of now. I realize that its my own fault for not doing my due diligence, but it doesn't change where Im at now.

The woman call me back this morning and said her husband bought the car basically in the condition its in now. The only work he had done to the car was maintenance type work to keep it drivable... She is supposed to call me back this afternoon with the info of the shop that they bought it from (Local restoration shop).

I explained the issue and told her i preferred to just give her the car back for purchase price and she stated she wasn't in a position to buy it back.

I dont want to get anyone in trouble, nor do i want any trouble for myself. I can't keep the car knowing that there is a possibility that it isnt legal. I also can't really afford to take a 9000 loss.

I will attempt to speak with the shop they bought it from and maybe they have a reasonable explanation for the inconsistencies

If not i have no choice but to do the legally and morally right thing.
