My 2009 c300 sport's factory warranty is about to expire within the next week or so.

I know I have 1 year extended as per MB and they claim it doesn't "cover as much"

Any recommendations before the car hits 50k? Only thing ive done to the car being the 3rd owner is an oil change at 45k, (can't rotate the tires), cabin air filter change at 48,500. I believe the car is due for a transmission service and not sure what else. My nerves have gotten to me thinking once the car hits 50k im going to be doomed (bad experience with an A4 a few years back has made me this way)

Help me out

 

Honestly I have been dealing with Mercedes for a while and as long as you take care of them they're good. My 2000 S430 still runs amazingly and i haven't had a problem in years. I would just go get it checked at your local Mercedes dealer for anything.. Good luck
