LV Cars Sold me a lemon of a car Las Vegas Nevada

 Bought a BMW 550i from them and have had major issues since day one. First the car started somking terribly at extended idles. I have had electrical issues including tire pressure computer, park assist, navigation are all inoperative due to previous water damage. I have been pulled over by the police for smoking and told it will not pass the next smog test due to smoking. I brought the car to two repair facilities 2 days after purchase because LV Cars refused to look at it. Both repair facilities said it was a $7000 repair to the valve stem seals and there was brand new thick diesel oil to try and hide the issue. I tried to get them to take it back or repair it and LV Cars kicked me out of the showroom and out of the parking lot because the car was smoking. They will not help or take any responsibility.
