I've rented a bay there whenever one of my cars needed work. Prior to my first rental, I had to watch a video and sign a release. they drove my car in and put it up on the lift. Understand, this establishment only rents you a lift and tools. It's not meant to be an ordinary mechanic's garage.
As the owner of a couple of foreign cars, including a diesel Mercedes, it's hard to find places that won't take you for an arm-and-a-leg just to change the oil. I bring my own oil, filters and tools. I'm usually in-and-out in an hour.
There are entire tool chests for rent (with air tools) for an additional $10/hr. They can order whatever parts you need, from oil and filters all the way to crate motors/transmissions. There is access to online Mitchell Manuals if you need a reference materials. I just wish they had a parts cleaner.
If you get in over your head (I have), ask for Rick. He will help you or take over the job for a reasonable price. I've seen him working on Ferraris, Porsches and Mercedes.
There has been some confusion. I've seen other "professional" mechanics in there. Remember, they rent a bay just like you. I've seen some pretty cheesy activity by some of these guys (Hello, Don). If Rick works on your car (at your request) you will get a U-Fix-It receipt. He stands behind his work. He did on one of my cars.
