Grain Valley Auto Repair

Andy is so friggin good it’s scary

Excellent. Got our truck in on very short notice and did a great job.

Detailed information, great work, easy to work with. I'll be using these guys again!

Awesome, awesome place. My truck blew the radiator as I was dropping off my trailer at the RV place down the road. I called up Drew and drove the truck over. They had the part on hand and fixed me up immediately. I was out the door in about an hour and they even gave me a military discount. I told them I'd be back for any diesel repair, even coming from 45 minutes away, and I meant it. Great shop.

Hands down, this young family owned and operated business. I was so stressed out over the heads going out on my new deisel truck. First time deisel owner. Had no clue as to where take it and who to trust. Landed at Drew's and thank the Lord I did. Honesty and integrity is what I experienced at Drew's. He could have sold me a new tranney but because of his integrity, he saved me thousands of $$$$$. Andy, you are our lifelong deisel mechanic. And your wife is so sweet. I will recommend you to anyone. Bless you and I see your business exploding in growth. Ya'll are awesome! Thank you so much.

Drew’s Diesel is the most honest shop around. They are more than just diesel mechanics. I’ve been taking all of my vehicles to Andy no matter what shop he worked for. I recommend Drew’s Diesel to everyone I know.

Been dealing with Drew's for several months. A few of our vehicles had reoccurring issues, and a couple other shops could not get the problems fixed perm. Drew's did, the first time. Andy is our point of contact, and I want to say that the courtesy and professionalism we get from Drew's is outstanding. I'd recommend them to anyone.

Great service! Fast , Save me money on parts. Great shop.

Absolutely wonderful, knowledgeable, and honest!

With all the good reviews, I figured I’d give this guy a chance for my first upgrade (FASS). Was not disappointed. Seems like a great guy. Looked over the installation when I got home and all was well. No kinks in the hoses, no leaking fuel, just done the way it should be. He also noticed another issue, pinion seal and informed me of the issue and noted my warranty would cover it. Helpful info from a mechanic. Will be going back for sure for all future upgrades and problems.
