my 2000 s500 has 52k miles on it, can you guys let me know when i should change fluids, other maintaince, coolant flush, ect. thanks greg

 

Only change the oil if it is super dark, and burnt, then replace.

As for Transmission, (ATF) Automatic Transmission Fluid. If its a nice red its fine, and if its a dark brown, or brown, it needs to be replaced.

check your brake fluid once every month, just refill it if its low,
