Let me explain, went to the dealer near me for oil changes for my then 2015 sps all in 79.95 plus tax. Ordered 2019 sp widebody, delivered October, 3000 miles on it. So in I go, and service writer tells me you will need an SRT oil change. I did not ask what was that, after all they were going to go over the car and check air in the tires. that would be 139.95 plus tax. I did not care, I had a secret weapon in my pocket. Half hour later he says your all done, and I say oh by the way, this is my 5th oil change, its FREE. He had no choice but to honor it. That's the latest scam, that's why some refer to them as stealerships.
