Por quality repair work

I bought a vehicle from this dealer. Upon testing, the car seemed to be in fair condition. It was declared to me that the car was involved in an accident, but that it was repaired and in good condition. However the car started giving problems and we had it checked only to find that the repair work after the accident was of poor quality. The dealer is now refusing to pay for the repair work that needs to be done to render the car safe to drive. I will not recommend this dealer to any person. I also note from the previous reviews that the only positive review was made by the dealer himself
