bad use car from dealer

I bought a used car from Sutherlin Nissan with Vance. He was very cooperative with a making a sale, but did not care of offering customer service. Having the vehicle less than a month, brakes were completely gone. My wife and daughter were in the vehicle when the brakes went bad. I could have lost both of them. He never offered a carfax or shows me any inspections of the vehicle. I went to Sutherlin to try to fix it and they gave me a hard time. Now my AC is gone and they knew it was bad and they put a lot of Freon to keep it cool. David recommended I get extended warranty he said it covered the vehicle, it did not. I went back to see what they could do for me, basically he said IM SCREWED and I was pissing him off. WORST DEALERSHIP EVER!!!! I would never buy a vehicle from them. All they care about is making a sale; they will lie just to get it. Please everyone DON'T get a vehicle from there, it almost took the life of my loved ones, that’s how much they care.
