1) Check internet for the car I wanted. Cabriolet E-350
2) Realize the car I wanted was right around the corner at a reasonable price.
3) Show up.
4) Take the keys and drive the car by myself for 30 minutes.
5) Two days later have my mechanic come over and look at car.
6) Call dealer at 5:55PM on a Friday. He runs my credit delivers the car to my house 7:00 PM. He UBERS back.
Could not be easier.
