The sales pitch sounds great! Carmax is unlike any other (they tell you) when you are looking to purchase a used car, because they provide a 30 day warranty "in writing". Sales personnel at all levels tell you that you have 30 days to visit the dealership's service department for "any" problem encountered under this warranty and it will be fixed. Upon bringing the car back for an item "covered" under the warranty, they refused to fix the problem, and now their response to my inquiries is, "Well, it is a used car, " and they repeatedly refuse to honor their warranty!!! The corporate customer care line is no help and simply repeats, "Well, it is a used car, after all." However, specific items that are supposedly covered under the warranty are NOT covered if they meet Carmax's standards, which are not provided to the customer until an attempt is made by the customer to have "30-day warranty" work completed. We are very disgusted with this company, its service personnel, and its managers, and will never purchase another car from them in Wisconsin or any other location. We also purchased an additional 75, 000 mile warranty, which allows us to take the car to have work done elsewhere, which we fully intend to do. My recommendation: go somewhere else.
