C8 Z51 owner takes car into a Hendricks dealership for repairs which they have for some days
Owner goes to pick C8 up to see the car now has over 15 miles driven on it
He had set the PDR so that it records every time the engine is started
He reviews it to see the 2 tech's who seem not to know how to speak English drove over 15 miles and at one point over 103 MPH in a 65 MPH speed limit

Notice how they get right onto the left passing lane and never move to the right and seldom use the turn signals.
Check at about 17 minutes into this video to see over 100 MPH
