Stay far far away from Lorentz Automotive/Lewisville Muffler…read more I called asked for an appointment to replace the Catalytic Converter on my Jeep Cherokee Sport 2001, 2 WD. Ballpark they quoted me $400-$600. Dropped my car off when I picked it up the bill was $996, and what they did instead of replacing the Catalytic Converter like I requested. they cut it in half and only changed half of the Catalytic Converter, then said "oh you need to get the back part installed soon it's going out.". They cut the Catalytic Converter in half only changed half if the Catalytic Converter now they are asking for $700 just for the missing half. I called Huffines Jeep and told them never to recommend Lorentz Automotive/Lewisville Muffler to anyone again. They are shocked that the Catalytic Converter got cut in half. Now I am looking for someone to install 1/2 , Huffines said they only install complete Catalytic Converter

Lewisville Muffler is Amazing. They have great customer service, and will go out of their way to…read morehelp you out in anyway possible. I went there hoping to get a quote on replacing a catalytic converter on my 07 malibu. I had an idea it was going to be around 600. They told me it was actually both of my converters, which devastated me. I knew I couldn't afford it. Then, they actually took the time to research and look for ways to save money. The guy that helped me out actually found a special coverage warranty for my model and my converters were actually covered. I set up the appt with Huffines Chevy, and they did the work and replaced it free of charge. I had tears in my eyes. They truly made my christmas special, and I can't thank them enough. If you want to be well taken care of, go to Lewisville Muffler!

Took it to Christian Brothers, then to Lorentz Automotive, both gave absolutely bull crap diagnoses. Took it to Brian's after several headaches, and one of their guys named Joe took excellent care of the problem (got a new starter and it was handled promptly). Now she's purring like a kitten. Guy at the front desk was respectful and honest. Overall, pleased and have a new go to shop.

Got my truck back a few hours later and very pleased overall. Going to use this company as my mechanic going forward on my truck and my wife's SUV.

Excellent experience! My 2003 Acura TL, S-model was completely dead on July 4th (of all days!) when…read moreI came out to start it around 5:30 PM. Had to call Roadside Assistance to jump it so I could get to O'Reilly's Auto Parts for a new battery before they closed. They said it was the alternator not the battery. Contacted DFW Mobile Repair and Hamm responded immediately with a price quote to fix it. Set up the appointment for mid-afternoon the next day, July 5th (Sunday, on a holiday weekend). Hamm was certainly knowledgeable, and after testing, said it was BOTH the battery and alternator. He replaced the alternator (which he had brought, having had my prior information as to car and model) and then drove to O'Reilly's nearby for a replacement battery which he then installed. In short, Hamm was responsive, capable, courteous and efficient. DFW saved the day (although I lost most of the holiday weekend with the problem!). Pricing wasn't cheap but was competitive I'd say. Give DFW a shot. Their customer service and mechanical work was outstanding. They also have a shop in addition to their mobile repair service. I will certainly consider them for all my future work!

They have always given us estimates and services before the service is started. I have never had a vehicle that wasn't repaired or recommended repairs that we decided to or not to replace.. We had one 2013 SUV with about 80,000 miles that to be repaired for any long term use needed about $7,000 to $8,000. We that car traded to an automotive dealer with full knowledge of the work that needs to be done. In my humble opinion they are the best in Denton Count.
