First time buying a car at a dealership purchase went smoothly, but took longer than I d expect waiting over an hour just to pay. On my way home noticed that one of the headlights was out so I texted the salesperson (Shane) explaining my discovery. Waited until next day and after no responses I called dealership 2x asking to speak with him. After being told he was busy I asked to. Speak with a manger after exposing the situation of the light out and how I wanted it fixed he tried to tell me that it was wear and tare, even though I had bought the car just the day before and the car had been through a 168 inspection and they signed off on the light working he still insisted it was wear and tare and nothing he could do. After I mentioned I had a picture at the dealership with the light out before taking it home. This made him quickly change his approach and said that he would talk to his boss and contact me about it the next day. I waited and after no call I contacted the salesperson again and told him what the manager said. They made me come all the way up to the dealership (50 miles) out of my way to get it fixed. First and last time buying a car from a dealership.
