Just brought a car less than a month ago. Car begins to make noise. Took it back and was told the two rear tires were to big and although I have a warranty they would not replace them. They would like $356. I'm very sad that they won't correct the issue. This is my second car from them and after this I will not buy another. Misleading as to what the warranty covers just to make a sale. Beware!
