Did the car come with service history documents? If not, checking and replacing fluids and filters is a good way to get to know the car. Authorized and bootleg CDs of barely passable factory service manual scans are available. Or spend the money on printed volumes if you’re a DIYer. Oddly, the CDs don’t include transmission service volumes.
