Brought my truck in for an oil change and to check some electrical items. Dropped off at 8:15am. Called at 1pm for an update. Was told electrical is completed and we just needed the oil change. They told me to call back in 2 hours.... Called back at 3pm and was told it still needed the oil change and that would take about half hour.... Then she said to call back at 4:30pm... Have now arrived at 4 to find my truck parked in the lot... Asked to pick it up and was told to wait in the waiting room for the paper work. I have now been in the waiting for 35min and still no paper work. Pretty bad it takes 3.5 hours for an oil change. I definitely do not recommend any service at this garage. I will never bring a vehicle back here.
