I knew also that I would be silly not to buy a car from myself. I wanted the credit for selling a unit, even if it was to myself. I was down to 3 used Priuses, two 2011's and one 2008. I tried starting all of them, and only one started in the frigid weather. It's very common for cars not to start on car lots because the battery gets bad very quickly if it's not used. It's called lot rot. The two 2011 Priuses were nearly identical, with a similar number of miles, so I chose the one that started. Even though I know all about lot rot, I opted for the one that started. I closed the deal on myself.
I had never driven a Prius except around the lot so I didn't have direct experience with the amazing gas mileage and other features. After 5 days of driving it, I have to say, it's the most efficient and wonderful car I've ever driven. I programmed one trip out to my parent's house to see what mpg I got, and it was around 46 mpg. The next time I drove to their house, I changed my driving habits so that I could increase the mpg. That time I got 50 mpg. There's a panel on the Prius' dash that lets you see how your driving affects the mpg in real time. It's fascinating to watch, but a bit dangerous, since I've caught myself a few times paying more attention to it than the road. I also love seeing how my driving affects the recharging of the battery. For example, every time I press on the brakes, I can see how the energy is sent to the hybrid battery.
Until Kansas City get a supercharger, I think the best car to get is the Prius. It truly is an engineering feat and a real joy to drive.
