Glenns Performance Automotive - Denison (TX)

1 /5 Jen Colvin: I wish I could give this place zero stars. What started as a simple repair turned into an absolute nightmare that cost me time, money, and incredible frustration. I brought for a car upgrade. The initial quote seemed reasonable, and the staff appeared knowledgeable when I dropped off my vehicle. They said they could do it, only to turn around and break it all and then tell me I have to pay for it. This is poor and dishonest service. Save yourself the headache and find a reputable shop elsewhere. This place clearly doesnt stand behind their work and will leave you worse off than when you started.

5 /5 Melissa Finn: My husband brought our Ford Escape there for head gasket issues, and they took care of that swiftly. Then they helped him with a hole in his oil. Then they saved my mother in law two grand by fixing her AC when the dealership wanted to take her savings by doing unnecessary work. These people are honest, extremely hardworking and I highly recommend them. Integrity is important, and Glenn has it. We even brought a car we were potentially buying, and Glenn took a look at it for us before we purchased it. They price fairly, Im not saying theyre the cheapest, but the quality of their work allows you to feel safe in your vehicle.

1 /5 Michael Monteagudo: Terrible service, “fixed” a problem with transmission which led to transmission going out completely, lied about details that were given, owner cussed out my wife, sneaky people doing “work” to extort, will be filing a lawsuit

5 /5 Thomas OSullivan: I cannot express how thankful I am for the folks at Glenn‘s performance Automotive. I broke down in Denison and was able to limp to their shop. They got the car in the very next morning and made the repairs both quickly and were far more cost-effective than the shop that did the original work. They also gave me everything I needed to get my money back from the shop that had done the faulty work. Glenn‘s performance automotive is fair, honest and fast. Thank you guys!

1 /5 Nickolas C: What a joke! No idea how to work on newer cars. Broke parts due to their incompetence and tried to charge for it.
