Called to get an appt for 2014 cruze, heater not working, advised I needed a loaner car. Cant get appt for two weeks. Day before the appt I get a call saying they may not have a car available, but could give me a ride home. I NEED TO GO TO WORK-NO HOME. Went in for the appt and they did have a car. Called before I left work, oh they didnt have time to work on it. They called me next day and told me what was wrong and it was under warranty and were working on it. Go after work and oh its still not ready because they dont have the parts, (nobody bothered to call and let me know) So now I have the loaner car over the week end. Monday get a call and they are working on but still could get it done. Tuesday, called and said oh by the way its not under warranty and instead of costing $289 its going to cost you $660.00!!! But they would see what they could do and they got it down to $605. I will never go back to this place and will never buy a car there. Worst service I have ever had there.
