> I feel like any repair at the dealership costs at least 50% more than if you go to another establishment.

It’s entirely dependent on the market and region. Sometimes it is cheaper to go to the dealer depending on make and model. It also depends on where you live and the availability of mechanics and parts.

There’s also certain things that are cheaper at a dealership. My father is a mechanic and still brings his truck to the dealership for oil changes because they will change the oil for literally less than his shop can buy the oil for.
