If you have cleavage, display it. If you have a good body, show it. The salesman will be distracted, and give you what you want.
If you don't have any of the above, getting a 2007 is a good idea, 'cause the 2008s are on the way, and Mr. Dealer will wheel and deal to get rid of leftover stock. Remember, the dealer is usually paying interest on the cars sitting on his lot..he has to buy them from Ford, and usually, unless the dealer is filthy rich and can front the money himself, they go through a bank or financial institution..so, the longer a car has been on the lot, the more it's costing him, the more eager he will be to get rid of it. Read.."Don't Get Taken Every Time" by Remar Sutton. It is informative, funny, and will teach you a lot. Now, there are those on here that will poo poo Mr. Sutton's book. Ignore them. Read the book. Then, with you new found knowledge, and that low cut top, you'll do just fine.
