Ok so 15 minutes was an understatement, but I meant, why should it cost so much/ take so long to do?

Jacking up the car and putting on jack stands would probably be like 15 minutes, but from there the oil pan should just have like 10 bolts to remove, then scrape old gasket material away, then reinstall new gasket and sealant and reinstall oil pan. Shouldn't be too difficult to do.

UPDATE: Mom says dealership says you have to remove a crossmember and A pipe to remove the oil pan? Does the A-pipe run underneath the oil pan?
