Cornerstone Auto Service

Cornerstone Auto – A True Gem for Foreign Car Owners If you’re searching for a reliable, honest, and highly skilled mechanic who truly cares about both your vehicle and your wallet, look no further than Cornerstone Auto, run by Tony and his incredible team. After my recent experience with them, I can confidently say this is one of the best automotive repair shops I’ve ever dealt with — especially for those who drive foreign cars. I brought my Mercedes C300 to Cornerstone Auto after dealing with ongoing issues that no one else seemed to be able to fix. I had previously taken my car to a few other places, including some of the “big name” shops like Astorg, only to be met with sky-high labor rates and rushed, incomplete service. From the moment I walked into Cornerstone Auto, I could tell it was going to be different. Tony greeted me personally, listened carefully as I explained the problem, and took the time to ask questions to fully understand what was happening. That level of genuine attention immediately put me at ease. What truly stood out was Tony’s diligence and attention to detail. He didn’t just plug in a diagnostic scanner and call it a day. Instead, he methodically inspected and tested different systems to pinpoint exactly what was wrong. It was clear that he takes pride in doing the job right — not just fast. He worked diligently to resolve the issue, keeping me informed along the way so I always knew what was being done and why. When I picked my car up, it ran better than it had in months, and the problem that had been plaguing me was completely gone. In addition to the high quality of their work, Cornerstone Auto’s prices are refreshingly affordable. Compared to Astorg and other large dealerships, Tony’s shop charges a fraction of the price without cutting corners or compromising on parts or service quality. It’s rare these days to find a shop that combines expertise with fairness, but that’s exactly what you’ll get here. For anyone tired of being raked over the coals by extremely high hourly labor rates, Cornerstone Auto is a breath of fresh air. The staff at Cornerstone Auto also deserves recognition. Every person I interacted with was polite, professional, and genuinely courteous. From the front desk to the technicians, everyone seemed focused on customer satisfaction. It’s clear that Tony has built a team that shares his commitment to honesty and excellence. In short, Cornerstone Auto isn’t just another repair shop — it’s a place built on integrity, skill, and respect for customers. Tony and his crew go above and beyond to make sure you leave happy and confident in the work performed. If you own a foreign vehicle and are looking for a trustworthy mechanic who delivers dealership-quality service without the dealership price tag, I highly recommend giving them a call. Cornerstone Auto has earned my trust and my business for life. Five stars all the way! ⭐⭐⭐⭐⭐

I took my Audi here and absolutely had a great experience! They fixed the issues with my car and it was a very pleasant experience! Knowledgeable honest people and a nice clean shop. Highly recommended!

The service advisor was outstanding. But…when I looked at the diagnostic sheet that was left on the seat of my car was for a different car. So, aI do not know what codes were found on my car. I knew something was wrong when I noticed it was the wrong year, mileage and VIN number.

This is my first experience with Cornerstone Auto Service. They went above and beyond working with me scheduling wise as I had to change the schedule due to health reasons and they were very accommodating. Then the service performed on my car was top notch. I will feel very comfortable with them servicing my vehicles from here on out.
