New to Car repairs, is this fair? 2017 Kia Sorento

I have never had a major car repair in my adult life and want to know if this is fair for what my repair cost. I would like to use them again the future as they were extremely quick and insightful on explaining what happened and would like to work with them again.

My car had an engine light on when I started it last week and the car was sputtering. It was an engine misfire and needed an oil change as well.
