Cactus Jack's Auto Repair We were towing our little Casita…read moretravel trailer in an area that is about as far from a Mercedes dealer as you can get in the USA. We stopped briefly at a dollar store to grab a couple of things and the engine started misfiring and the check engine light came on! We were nearly 300 miles from home. Nearly the same from the nearest dealership! But it seemed to be running semi smoothly above 2,000 rpm, so proceed the 20 miles to our next camping destination and take it from there. It was Saturday afternoon. We will get nothing done until Monday, so we might as well relax. Over Sunday, I checked on local auto repair businesses. I found a first choice. Went there Monday morning, first thing. There was a for sale sign up and it was locked up. Came across a second, quite by accident, but their ODBC tester had been stolen. Also the shop was FULL of dust covered cars, just sitting there in various by states of disrepair and disassembly. They recommended that I go to the local O'Rilley's and have them diagnose the problem. He got out his pocket sized tester and informed me there was an ignition problem with the number four cylinder, maybe the plug, maybe the coil, but "Cactus Jack's Auto Repair" had the best ODBC tester in town and they also had a "crackerjack mechanic". I drove over there and met "Kris". I instantly felt a whole lot more hopeful. He got out his big ODBC tester and confirmed that the number four cylinder was the problem. It was at least the plug (I was due for new plugs anyway) and probably the coil too. He said he could have the parts by Tuesday at two. I showed up at the appointed time and two and a half hours later I was back on the road, running like a dream. I experienced only sound, confident, competent, professionalism. I would feel comfortable taking this car, or any other vehicle to Cactus Jack's for ANY mechanical issue. Solid, honest customer service, at its finest. I highly recommend this establishment
