Confessions of a Car Salesman via boingboing
Interesting article on car sales, from an author who went undercover as a car salesman; definitely a must-read for anyone looking to buy a car, but it's an interesting look at sales and sales tactics from the side you're usually not on in a car purchase.
Especially note the "up to?" technique. I recognized this as something I'd been hearing during car shopping, but only *after* I'd been car shopping.
