I purchased a car from a car dealership about 3months ago. When I purchased the car we agreed to $4900 with everything included transferring of the plate, registration and everything I needed. The dealerships owner which is the person who sold me the car and has hos signature on all the paperwork called and said he wants $1000 more for the car. I said no we agreed to $4900 and that what the paper work says. He did not transfer my plate or register my car so I cant drive it or register it or the plates because I have no title but he has my money. Can I sue him?
