This was the worst experience I encountered with a dealership. I came in to buy a used car and I spoke to them about the tire sensors being on. They said they would fix the sensor and get it ready for me to pick up. The day comes and first they tried to charge me more money without discussing anything with me. On top of that the sensor was still on. They told me to come back in and they will fix it. I drove back and they still didn't fix the problem. They told me to go to the dealership myself and fix it and let the other dealership call to confirm. Guess what... no answer. I was stuck paying for what they said they would fix BEFORE I leave the lot. They are the worst salesman I have ever dealt with. Avoid!
