Cars Trucks And Credit

We are a family of 5 that waited a year to buy a van that could safely and comfortably seat us all. We bought a van from Cars ,trucks and credit with a... non- working ac. After all was said and done we now realize the the deal we though we were getting was no deal at all. It was cold outside so the ac deceivingly felt cold when it was first turned on. That night not even an hour after purchase we realized it did not work at all. We contacted them the next morning and they sent us to have it charged but come to find out it would cost $700 to have working ac at this time we were told we signed the as is contract and we were on our own.So now we are back in our old car because it has working ac.This purchase was a huge disappointment and brought us nothing but heart ache. We spent what we had on purchasing this van and can not afford $700 to fix it anytime soon. They knowing sold this car with a major defect to a family with small children.
