My 2008 E-350 Benz

What is your question?

I have a 2008 E-350 Benz. It went in open air storage in 2016 and sat there idle for six years exposed to all of the elements of each season (Maryland).. Recently I took the car out of storage and needed only to replace the battery and tires. Prior to putting the car in storage it had a tune up and oil change performed as well as any other needed service. The car starts and drives great. My concern is about the fluids that has been sitting in the car all that time, should I have them and will it matter if I don't.
