i have a 96 sc 300 5 speed and its got like 89,500. when you hit 90k miles, what maintenece is required? or does anyone have any links or advice for what i can do myself and what is worth getting the shop to do? also i am a big DIY'er, so if its oil/ oil filter, air filter(think im gonna throw in a K&N), tire rotation, etc. i would rather just take a saturday and get a little greasy under the hood. i have heard that the timing belts go bad around this time. any advice or tips would be highly appreciated.
