Hello, I recently purchased a 2011 GL 450 with 90,000 miles. I've heard about the maintenance and upkeep Mercedes require but I haven't owned one before and I'm trying to get an understanding of the future maintenance costs I should be expecting and how I should treat the car as the miles add up. I wanted to get some information from people who have owned MBs before so I can get pointers on what to expect in terms of how much the 2011 GL 450 will cost me to drive and maintain.

Thanks
