The impact gun had one job… and somehow started a dance party. 😂

The service team caught the rhythm and things escalated quickly.

If your vehicle needs some attention, book your next service at Mills Motors, we promise they’re even better with tools than they are with dance moves: https://buff.ly/45vw3Ov

Cold mornings hit different when your truck is actually ready for them ❄️

Allan is taking us through the 2026 GMC Sierra Denali and a few of the features that can make colder drives a whole lot more comfortable.

If this sounds like the kind of truck you want for the colder months, come take the Sierra Denali for a drive at Mills Motors or browse our truck inventory: https://buff.ly/387o9bz

Now it’s your turn, what’s the greatest GM truck of all time?
