I dunno about that.April Fools right?
I once bought a 2000 BMW 528. First three years all maintenance was included. It had a series of 5 lights on the dash that when all were lit you were supposed to take it in for service, and they would reset the lights. It wasn't just mileage based - other factors were included. I had to lean on them to give me my free oil change when a year was up and I only had 3 lights lit. If I remember correctly I had less than 6000km on it. It was synthetic oil.
