Doesn't the test drive come *after* you ask "How much?"?
Honestly I am surprised at the attitude that merely showing up at the dealer means that you locked into a purchase, and you can't find out the price until after halfway through the purchase.
In my country (not the US) it is normal to negotiate price before even looking at the car (for new cars, anyway).
Whatever quote they give you is then locked in, they can't change their mind when you change your address details.
Not that we don't get screwed, we do, but that's due to a different cause.
Before you request a quote? I was suggesting getting the quote before buying.
