they offer State inspection sticker with oil change service

I came in to get an inspection and oil change done with fluids checked. Got exactly that. plus when I asked if they had any extra coupons, the manager was kind to offer me one. I used to go to my local auto repair shop, but this location which is closer to my work works out well. I also did not feel looked down upon as a female customer(due to my lack of knowledge about cars) by the technicians as I often did at my old repair shop. I will be returning.

went to sonner lube for a oil change, employee called me out to show me there 17 point check they do, he recommended a transmmsion flush, I did not have any copouns and he offered me $15 off, was verry happy with service and employee,, they also vaccum car which is a great plus.
