What People Say
We are on a family road trip from Minnesota to Glacier and beyond and our GMC Duramax kept blowing through fuel filters. We took it to a local dealership in Great Falls and they told us it needed new injectors and quoted us an outrageous price. Luckily, someone suggested my husband call Casey! Needless to say, he squeezed us in, gave my husband a ride to the campground, and fixed us up all for an unbelievably reasonable price. ( By the way, it didn’t actually need new injectors.) He saved our vacation! We HIGHLY recommend doing business here. Thank you, Casey!

★ ★ ★ ★ ★All to often in this day and age we become complacent about customer service and as consumers we accept it. Not at this shop. I can not say enough good things about this place. Great people. Great attitudes. Great service. Great products. Great results. I have been here several times on my quest to make my rig strong enough to pull what I need it to, so my review isn’t based in a single sale. Bar none this place and it’s people are amazing and not just to me as I have seen them treat everyone this way. Compared to the actual vehicle dealership, this is 5 million times better. If you need something done to your truck then don’t make a mistake by not having your work done here.

★ ★ ★ ★ ★Casey is one hell of a guy. He took me in on the spot to take a look at my truck. I thought I had a fuel or rod knock in my 05 LLY, turned out my ears were just messing with me, but nonetheless, great guy and very knowledgeable. Thanks again Casey
