Just had my 1200 mile service done yesterday. Got the total BS line from the SA telling me that the break-in service unlocks more power
.
Oil change and diff fluid change were performed and car performs and sounds just like it did before the service so at least they didn't screw anything up.
One somewhat funny note is my dealership now takes video during service and they informed me that my car has summer performance tires and aren't designed for snow (really????). They also let me know that my car is blue which I wasn't aware of.
