Best/most trustworthy car mechanics?

Need my car to get me through college and while I’ve been getting regular oil changes and such at Strickland Brothers, I want to get my car checked out to see if there is anything that can be done to hopefully keep it running longer, especially since I’m just working over the summer and have some extra money to put towards it. I have gone to the Mazda dealership a couple times for bigger issues and have found it to be a bit of a headache in a few different ways, and while I don’t think I’ve personally had any issues, I have heard of women being scammed at smaller repair shops.

Thanks!
