There's an old saying: 'People like to buy from people.' When it comes to buying a car, I HATE dealing with people. They mess things up, they don't listen, they try to upsell me every step of the way. If you are genuine and really into helping others (think Apple Store), great. But if you are providing. the typical dealership experience, you are doomed to fail. If you work at a dealership (or any retailer), you have to be an expert. Tell me something I can't find out on my own, on the internet, or by looking in a brochure. Otherwise, I don't need your help!
Product demos are super great but when they don't work, I have to go somewhere else. What's the point of a product demo if it is broken, taking up expensive shelf space?
