Car rides and drives like nearly new!
I own an 07 F-150 XLT (5.4 Triton Eng). 3rd owner with 154,000 miles on it. Im sure darn glad I found a reliable shop to get all the bells and whistles serviced to make this truck a MONSTER of a daily driver. Thanks to this team, I have affordable and effective care of my truck to avoid having to drop thousands of…
Auto Tech has always provided honest & professional service! I was in last week for tranmission seals leaking & they showed me the leaks, ordered parts & installed in great time. The entire team is fantastic - courteous, friendly & truly concerned about my safety . I won't take my car anywhere else! Thank you Autotech! Donna
Excellent customer service!
My first experience with Auto Tech could not have been any better. Great communication, service, and cost was reasonable. I did have to push them to look at filters rather than just tell me how long since Carfax reported they were changed, but they did. I’ll definitely come back and let others know about my great experience
I am so happy to have found a good place for my car's maintenance and repairs after moving to St. Charles County. They are honest and don't try to get you to have unnecessary work done. The staff is friendly and work is good and efficient. I had to wait and my car was finished quicker than I had anticipated and done well. Would definitely recommend.
Scheduled an oil/filter change along with tire rotation and emissions testing. They are always friendly and never try to push upsales on work. Always inform you of maintenance without the approach of the quick oil change folks. Great place to trust for your auto needs.
Autotech did a great job!
I am selling the car that I have brought to Auto Tech for the past 12 years. They have serviced all his needs. But now the new car that I have will be coming to Auto Tech probably for the next 12 years as well! 03/32/2026 Brought my car in for inspection and emissions testing. It has 194,000+ miles on it, so it…
The only shop that touches my vehicles. Very dependable!!
They are always awesome! Friendly, great communication and reasonably priced.
From the moment I called to the moment I walked out the door car serviced nothing but professionalism. They talked to us about every issue then texted and emailed an estimate, we knew exactly what was happening and what they were doing. Being that the service was expensive, I will refer people all day long to…
Accommodating, kind, courteous and very professional staff.
Great job!
Love taking my vehicles to Blair. The Blair team is great! I wouldn't take my vehicles to anyone else. I trust them and their diagnostics100%. No upselling just common sense and education. A big thumbs up!
They thoroughly discussed everything with me
Great local shop to take your car. Been using them for over 10 years. Reliable, honest efficient and reasonable
I’m thankful for the service provided by Autotech over the years. I feel like they are honest and don’t try to oversell on what is not needed. I only trust them to work on our family’s vehicles!
I took my car in for an oil change and was alerted that my battery was not holding a charge like it should. I checked my records and found it was 4 years old. I’m so happy I won’t have a dead battery on a cold winter morning. Communication was great with Autotech staff. I missed their phone call but they followed up…
Great people and staff, highly recommend them!!!
