I've seen a few smarts around town but not yours. So far a silver/black, a blue/black cabrio, a yellow/black, and a white/black. When I took delivery they told me I was the 37th smart in South Carolina.
When you got your car there should have been a small booklet entitled "Scheduled Maintenance Guide 2008" that came with the package of owner's manual and misc. other booklets. That spells out everything that is done at the regular maintenance intervals. I am planning on doing an oil change after the break-in period (1,000 miles) based on the many people who have done that on this forum and found black, metallic-chipped oil. Nobody seems to think 10,000 miles is realistic and most likely a marketing ploy. Luckily, the smart is the easiest car in the history of cars for changing the oil.
If you don't have the scheduled maintenance booklet I think there are places on this site where you can download a pdf or check smartusa.com
