You don't mention where you bought the vehicle from originally, but we would have expected a vehicle history check to show that it had previously been written off. If you bought privately then you have limited recourse, as you would have to prove that the previous owner knew of its status when selling it, but if you bought from a dealer then you may have some grounds to claim that if you were aware that it had been previously damaged you would not have bought the vehicle. We would suggest starting with contacting the provider of the history check to determine why all of its history was not provided.
