Just hit 12,000 miles last night on my 2018 Charger Hellcat. Car has been a real treat so far. I had mentioned having a slight vibration between 77-80mph. I replaced the tires with Michelin PS4s and is smooth as can be. I have no modifications and plan on keeping stock. It is daily driver, though I do trade off with the Durango periodically. At half a tank and computer says 17.9 MPG. Hope everyone is well.
