Purchase went smoothly. Not more than a week after I bought the car it started leaking fluids. Took it in and they said they couldn't get it in that day. but would call us when they could. Never received a call. Took it back in a few days later and got it in. That was five days ago and still haven't fixed the car. I've been without a car this whole time until today when they brought me a junky loaner car. I was told they don't know when it will be fixed. I would be fine with exchanging it for another vehicle, but keep on getting the runaround. I don't expect to pay 30,000 for a vehicle and have it in the shop within a week.
