I disagree. When I bought a new car, I used the dealer's website to study their inventory. Once I found the make, model and features I wanted, I used the "days on lot" number to negotiate a lower price. (Since, as I understand it, dealers make payments on their inventory; therefore, the longer the car is sitting on their lot, the more money the dealer has "lost".) And when I bought used cars, using the internet helped save me thousands of dollars (close to $10K each time).
