It is up to the discretion of a vehicle dealer whether or not to sell cars at a loss. It all depends on whether they're having a good month or need to get rid of inventory. But, in the end, it's all about profit and loss in any firm. They do not have to sell the car if they lose a lot of money and believe there is no other way to profit. You cannot compel them to sell you the vehicle until you obtain a bill of sale signed by the dealer.
