Another tip, off subject a bit.
Always ask about the maintenance of the vehicle. When they tell ya it’s been perfectly maintained, always pull the oil dip stick....If it looks like black mud instead of clear and gold colored, it’s another con job.
My Chevy and Honda get the oil changed at the regular intervals and the oil has been black for as long as I can remember. Now at 190k and 140k and they run fine. All my cars have had dark oil. Even as a kid with my parent’s cars the oil was dark.
Bought a used Toyota Highlander at 100k. Oil still looks like honey after 140k!! It is pretty amazing (to me anyway)!
