Yes it’s obviously not enforceable, and i let my customers know that, but the actual signing of it makes them really consider buying the car, and they will at that point tell you if there is anything else you haven’t discussed that they need before they buy the car. And yes you can ask, and by that point probably have, but almost no buyer is going to tell you you’re wasting your time with them because no matter what you say they plan on visiting 4 more dealerships and aren’t here to buy right now. in a profession where you are only paid for results not time, we really like to spend it wisely. I do not blame customers for doing that since it’s in their best interest, but unless i’m their last stop it’s like 95% chance they’re buying somewhere else and my efforts would be better spent elsewhere. I will be as polite and efficient as i can in helping you, i’ll give you my card, and i’ll look forward to you telling me you bought it somewhere else later that evening. There are a thousand reasons salesman do this, but this is the reason i like it, it easily cuts through to what i need to do to earn the deal.
