I'm loyal to the Bend Chevy Dealership, they have changed my oil every single time since owning my truck. However, I do not appreciate them trying to "upsale" a bunch of completely unnecessary services to my wife when she dropped off my truck. The list of 30,000 mile scheduled maintenance does not reflex what the owners manual dictates. You want me to pay $746 for unnecessary services, including changing the rear differential fluid and transfer case fluid at only 30k miles. What BS! I'm glad my wife is smart enough to not get taken advantage of. Thanks.
