Stay away from this place if you value your time and money. This shop took 7 months to build a…read moremotor that I ended up taking to another shop to have fixed from the sloppy work done. Mark broke a bolt off in the main crank cap from the side. Then he did not put 2 bolts in the rear oil pane which goes into the LS rear cover instead he filled them with rtv silicone. When building a LS motor you have to use new head bolts because they are a torque to yield one time use but he used old bolts and charged me for new ones. Then he cut into the reluctor wheel while grinding on the crank so that had to be replaced. silicone was coming out everywhere so I could not trust it and I had to go to a better shop to have it checked. Motor has to be torn down and rebuilt, and parts replaced that Mark messed up. He thinks a person will not go through the trouble to sue him but for what I paid him and having to pay another shop to fix his sloppy work we will be going to court. There is alot of people saying the same thing and having issues with getting stuff done in a timely matter. Those good reviews are more than likely his people trying to off balance bad reviews. The review here on this page about a car breaking down at night and waiting until they opened is crap. Anyone really doing work with Mark is not getting anything fixed in that time frame so beware of the BS post here talking good about this shop. The crew je has now are not real trouble shooters so these posts are crap, The ine good mechanic he had died last year now he has guys going throught the motions with Mark being pulled in different directions to the piont the quality is no longer there. The review of the transmission repair is crap too he does not build or fix them. He might pull one and put one back in that someone else fixed but Mark does not build or work on transmissions so that review below is crap. The review the person posted here about going from California to Virginia is crap because this shop is no where near the highway for them to come off hwy 40 and find Marks shop out in the middle of Nicoma Park is absurd. There are many shops near the highway. Fake positive reviews. Cheap price is cheap work because you will end up spending more later to fix the work they do at Marks Machine Shop and Repair in Nicoma Park, OK. I attached pictures so you can see I am not lying.

I can't say enough positive things about Hard Luck Auto. If I could, I would give them 10 stars…read more While visiting their shop this week I witnessed their exceptional service, humor, compassion, quick wit, RESPECT, and willingness to go ABOVE AND BEYOND to help others. As a woman, this was the first time I felt comfortable and respected in an auto repair shop. Even though they were extremely busy, they never rushed through a conversation on the phone or in person. Every guest was greeted with a smile by Toni. Adam remembered a customers name from a year and a half prior. "Shawshank" worked on my car and went out of his way to explain and resolve the unusual problem (thank you, sir!). Even though their schedule fills up fast and you may be second or third in line, there was not one single disgruntled customer. The work they do brings an amazing energy to the building. If you need their help, go see them. If you are in a position to help them through a donation or by purchasing a shirt, please do! At the very least go like their Facebook page and spread the word about them. You never know who in your life may need their help. We need more people in this world like the staff of Hard Luck Auto. They are a blessing to our community and Oklahoma.

I've found Gray's consistent in all three. It's a small shop, so they don't handle every single thing, but Chris is quick with a referral or advice when necessary, though it's rarely been needed. Call ahead for an appointment and they'll get you taken care of!
