After calling Geico roadside assistance, a Carrillo's Auto employee came out to switch out the flat. Minutes later we discovered our spare tire was flat as well!

The tech went above and beyond to make sure we safely got out of DE!

I was also intereted in having a small dent dealt with in the rear driver-side door. I was not using insurance, rather I told them I was going to pay out of pocket. It took over a month to get an appointment to see an estimator, and when my appointment time came he walked around the car taking pictures for 5 minutes, then said he would be in touch. About a week later I got an estimate for over $10,000. He added things to the cost for which there was no reason to add, such as a brand new radar system for the autonomous braking radar. That radar sits behind the grill, which had no damage at all. He also tacked on paint blending with the front door and rear quarter, which elevated the cost added for the small dent. After receiving the estimate I asked him about what he had added and why, and asked him to revise the estimate to be more in line with my specific needs and requests. Since then a couple weeks have gone by and he has made no effort to get back with me. Complete radio silence. So my experience with going to Hertrich has been a complete waste of my time. Perhaps others going there and using insurance have a different experience, but I cannot recommend them to anyone, especially those paying out of pocket.

And to add insult to injury doing so about 10 minutes after most shops closed up for the day. **ENTER INTO THE PICTURE: John and Master Automotive Diagnostics** After giving John a run down of my problem over the phone, he was able to quickly troubleshoot the problem to include identify the root cause (a bad tensioner), call several stores to confirm availability of parts and provided SUPERIOR & QUALITY service. Not only was the service quick (considering working away from the comforts of a garage) but it was thorough, cost efficient, affordable and above all else, his customer service and communication skills were unparalleled. He was able to ease ALL worries, fears, and concerns within 10 mins of talking with him. He reassured me that I'd be home with my family within no time and that was warmly felt and received. I hope to never break down on the road again but he is HIGHLY RECOMMENDED and the FIRST call to make for anyone needing car repairs or is stranded on the road.
