I recently purchased a 2005 SL500 - I was told by the salesperson that I could use a babysmart booster seat in the front seat that would turn off the front passenger air bag whenever the seat was put in. After I got the car, I contacted the dealership to find out about purchasing the booster, but they said they didn't have any in stock and I can't seem to find anyone who carries them. Does anyone have any info in the Mercedes BabySmart Booster Seats (for kids 40-100 lbs.) or know where they can be purchased? Thanks
