My husband and I were traveling thru the area and needed an oil change on our 2024 Ram 2500. We made an appointment prior to our arrival and they were able to work him into their day. They performed the maintenance and their prices were reasonable. We would used them again without hesitation.

My Ram 3500 CTD needed a turbo replacement. Matt was very helpful on the phone, explaining my options, giving me a fair quote, and getting me in quickly. The truck is running great, and the final bill was the same as the quote. I appreciate that. I wouldn't hesitate to take my truck back to Demented.

I'm impressed so far. Had my truck in another shop and got a 30 grand quote. Had it hauled to them and saved 7 grand. I know i made the correct decision. I'll update the review after I get my Baby truck "as my granddaughter calls it" I've always said it's my last truck. New motors are spendy definitely worth it. Thank you Matt for taking care of my truck
