1995 C 280?'s

Just bought a 95 C 280 with 108,000 miles on it. I plan on doing an oil change, Change the air and cabin filters, and a new set of plugs. What else would be good to go over?

Are Bosch plugs OEM, and and what type of Bosch plug works good, or is there another brand that works good in this car? Thanks.

at 100,000 i would check the belts make sure those are in good working condition
