Just depends on the situation.

When I sold my last Tige last spring a guy brought his family from SoCal to Utah to pick it up. We met up at my house the night before. We all instantly hit it off. He and I talked boats, his wife and kids went with my wife and kids to the neighbors house to hang out with all the lady neighbors while the kids played in a sprinkler. After a couple hours we decided we were all hungry so we ordered a bunch of pizzas and hung out talking movies and whatnot. The next morning we drove to the lake for a lake test. All went well. We drove back to my bank and he paid the bank directly for the payoff with extra funds going into my account. They gave him the title. We walked out, done deal. We then took a bunch of pictures with our two families together with the boat. We met up with them later in the summer at their lake and spent the day with them surfing.
By the time we were done, I would have taken a personal check from him. Just a solid guy that I now consider a friend. We'll likely meet up again this summer as we have plans to be down that way. I know this is a rare situation.
