And JUST IN CASE the test drive goes bad WEAR CLEAN UNDERWEAR!!all jokes aside I coach sales professionals for a living. I can tell you the best sales people don't sell. There are three things that matter in a great sales person. 1. Care about the buyer. Care about them more than your quota / commission. 2. Listen. I mean really listen. Buyers will tell you what they want / need, but sometimes they need help to better define that need and 3. Be authentic. The advice you give should be in the interest of the buyer not you. If it's the wrong car or wrong time to buy, tell them. Some of the biggest sales I've ever witnessed was where the seller advised the buyer not to buy. Then helped them get to a position to buy, then they bought big.
