I always go a step further and take a pic of the odometer when I drop the car off. I had 10 miles slammed onto my Speed3 once and boy did that dealership pay dearly for their bull****. No one should ever do that. I can only imagine what the porters did to it. The only reason they had the keys was because I bought a second car from them and drove the new car home in the snow rather than the MS3. They needed the keys "in case they had to move it."
