Hello, I just bought my first smart car on saturday. So far I am quite enjoying it. It is a 2010 pure with 4500 kms but it has some options that I think are more than what a standard pure comes with but I may be wrong. Were the clock usually is, next to the tach I have the digital screen with the bluetooth which I can control with the small remote, what is this system called? It only came with one key, I would like another one, I know it has to be coded by Mercedes but can I get a key cheaper from somewhere else? Also I did not get a manual with it, is there any on line or elsewhere i can buy or do I have to buy it from the dealer also ? Is it safe to put aftermarket seat covers on since the airbags are in the seat, can anyone recomend any?
