Saw vehicle online and with USAA financing I came in to purchase. Finance manager made a mistake contract error after the purchase; I stated I wouldn't agree to change the contract but would be amicable to renegotiate. Sales Manager threatened either I change the contract in their favor or return the car after keeping vehicle for 2 weeks; Because of the continued email and phone call hassle, I returned the car, requested return of my vehicle and title, and purchased same vehicle at other dealership with same bank I was approved with. After I returned the car, had to wait 2 days for my vehicle to be available when I noticed dealership had damaged my vehicle. Spoke to Buick manager about damages and he stated he would not fix even though he knew damages were done by his workers. Had to leave because manager refused to come out and talk regarding fixing damages. Buick dealership in Duluth assisted with damages done to my vehicle and purchased without hassle. Have all documented via email to include pictures of my damaged vehicle. Will never shop or do business there ever again!
