    We found our former auto repair shop closed only to "randomly" pull into Mark Knaak's, Covenant Automotive, LLC today. While it makes sense to get an appointment, they performed mechanical service on two of our cars without hesitation. They were pleasant to work with, asked appropriate questions, provided information and excellent service second to none. Mark is a VERY experienced mechanic and able to work on almost ANY make or model. He specializes in "high end" luxury vehicles. Raise your prices, Mark! You deserve EVERY penny. THANK YOU. We'll be back!

    Mark was honest, kind, worked very efficiently, and made my experience at Covenant Automotive not only enjoyable but heaven sent. I will certainly be taking my Nissan to him and his team as long as they are in business in Tucson. Thank you Mark for your kind heart and excellent service!

    Very impressed! I just dropped in before 3pm on 2/19/2018 with my 2001 F150 Lariat, thinking I might need a fuel filter replacement..."Service Engine Soon" light was lit. When they checked, it was determined the truck was misfiring on #8. I thought I'd have to arrange another day to bring it in for the estimated 3 hour job; Mark assured me that he could get two guys to work on it right away, and if they had to go a little past 5, they'd do whatever was needed to get me going. Well, a whole set of plugs and a new coil, and they finished at 4:50! Amazing work!

    My stepdad brings in our cars to Mark and he does a fabulous job taking care of them! I took my Nissan Maxima in for an oil change and to get my splash guard nailed back into place. They took excellent care of my car and I am very impressed with them! Will be back with my husband's car for an oil change, and will keep coming back! The oil change is a great price for the service that you receive!

    Mark has worked on my Mercedes E350...and now a doge journey (only an oil change and inspection before cross country trip.) The service and above all, honesty you'll get here is just the best. We're moving east and will miss them!
