Martin is one of the nicest people I know and as a mechanic he is honest, fair, knowledgeable and very skilled. You won’t get more for your money than here. I highly recommend him!

My friend and I have taken our car to Wilberto at his garage twice this year. Both times he was very honest, fair and helpful. He seems to know how to diagnose and fix any kind problem with any car. He worked on my friends 2004 Mercedes Benz 340 CLK but I’m certain he can fix my 2014 Honda Accord. I plan to bring this car to him as well. Most importantly he isn’t what my dad used to call “remove and replace guys” who just keep guessing at problems, and removing and replacing parts, while you watch the bill get higher and higher. Wilberto is an old-fashioned style mechanic from the “good ole days”. He actually diagnosis problems and charges fair prices for his time. You can trust him to do the work and not rip you off. If you ever find a good mechanic, you must never move to another town because a good mechanic is so hard to find. Wilberto and his Agatha Garage are “keepers”. I’m never moving.

Very Dissatisfied. Brought the car in to see what was going on with it. We are new to the area, so we picked this shop due to the rave reviews we read online. Wilberto came out to check the issue out and told us that he could get to it after some time due to other cars that were scheduled to be worked on. Considering we use this car as our family's only means of transportation, we worked out how we would commute around town. When we got update with how the car was doing weeks later, he stated that there was another leak and they would have to get the part ordered. I responsed that we could make it work, we accounted for the extra part cost and figured he would have the leaks and issue of the white smoke fixed. We go to pick up the car about 2 weeks after the initial drop off, he states that the car could use some more coolant, which we understood, with it being a small shop, he didnt have the resources to top off the fluids, a standard at most shops. No big deal, we get it. We drove the car to get fluid and then went home. We felt confident that the issue was fixed. The next day, I started to drive to Boulder to start my regular day. Before I even made it out of Longmont, the car started smoking and saying my fluids for coolant are low, causing a bit of confusion on why this is happening being this is the issue we brought it in to get fixed. We are frustrared, and feel like we got cheated and now we are still out of a car and experiencing financial hurt from this incident. My wife is a teacher and I drive for uber, so not having a functional vehicle after hundreds of dollars and weeks in the shop is really hurting our family. If you are looking for a shop for your car, this IS NOT the shop you can trust.

I brought my car in for an AC repair and the price was less than half the amount the dealer was going to charge. The repair was completed the same day. Martin was honest and forthcoming. I highly recommend.

I highly recommend Agatha Auto Repair. Wilberto is honest and will go out of his way to make sure any issue is resolved. He is also very knowledgeable about aging cars and won't oversell you. He'll recommend what you need to keep your car in the best condition possible for it's age.

I could not recommend Wilberto and Agatha auto repair more strongly. He is very kind, always answers the phone, and has incredible customer service. You can tell he genuinely wants to do right by his customers and stands behind his work. Wilberto also went out of his way to make sure that I wasn’t stranded without a car by personally driving me home and dropping off my car once he was done with repairs. He also worked with me on scheduling and made sure I had my car in time for work even with his busy schedule. Thank you Wilberto!

Saved my tail. Needed an important part replaced, and the dealership was booked up for months. Called Agatha, and he immediately had the part I needed on order, and stayed in communication until the part arrived. Kept me updated on what he was finding after I dropped the car off. Fixed and running within a few hours. Will absolutely be going back.

Martin is an honest man. Comparing what he told me and did for me versus an Aamco shop: Aamoco told me the needed for open up my automatic transmission and so many things, which I was sure were lies. Martin proved me correct, there were two spots leaking and he explained what needed to be done, lower the transmission out of the truck, and replace the broken seals. I was able to drive 2,000 miles home to the east coast with no trouble! He was patient and worked with me on a couple of minor issues besides the transmission. I’m very happy I found his shop, and happier that my Ranger is still driving everywhere I need to go!

Not happy at all. I took my 4 wd truck in for transmission and transfer case work which I paid good money for. Within the warranty time I took it back in due to problems. My truck was in the shop for over a month I was told work had been done to fix it. To my surprise I was changing my oil and realized my 4 wd truck is now only 2wd because it no longer has a drive shaft from the transmission to the transfer case. I’m currently seeking legal action.

Martín provided the best customer service and fixed my wife’s CV axel and bearing faster than other shops could provide a quote. Not to mention, his quote was significantly lower than his competitors and it was backed by his warranty and integrity. My wife’s words on driving her fixed Nissan: “It drove great! Sound and vibration is gone and I finally felt safe again!” I look forward to having Agatha Auto take care of all my auto repair needs, thanks again!

I went in looking for help getting an upper control arm replaced, they noticed all the other issues I had going on without me mentioning them. Now most of my car problems are no longer, my suspension has never felt better, same for my steering. I can for the first time since I owned the vehicle get the parking gear to function. His customer service is absolutely beyond compare! 10/10 I recommend.

Martin is hands down the best mechanic that I’ve ever worked with. He’s honest, fast and caring. He’s helped me when I was at the end of my rope. If you live in Brighton and not taking your car to him and his crew you’re messing up. Will forever be thankful and blessed to have met Martin. Not only as a mechanic but as a person as well.

Brought my wrangler for work with p0365 and other codes in 2023/2024. He fixed it, and no problems for about a year. Then similar code popped again in 2025, and he fixed it for no charge. Fair price and good work, I appreciate his warranty. Would recommend.

Met Martin today outside of AutoZone by pure coincidence, but what a God send did it turn out to be. He over heard me arguing with a different mechanic shop about what all needed fixed on my car. He was so kind and wanted to help so he told me about his shop and offered to help me fix my car if I took it there. I drove my car to his shop and Martin and the other mechanics that helped/worked on my car, were all so nice and explained things to me so well. Thankfully it turned out to be an easy fix and my whole engine wasn't messed up and I was on my way in about an hour. Truly such a blessing, I'm honestly not sure what I would have done if Martin hadn't stopped and told me about this shop! Forever grateful!

With two elderly Hyundai's in the family it is important for us to have a good vehicle doctor, like a good vet for your dog. At Agatha we have found our perfect match. Wilberto has always taken great care of our cars and has saved us money. We have always received service in a timely manner and have always gotten our vehicles back on the road as soon as possible.

I needed motor mounts replaced. It was in my budget and the work was great. I had no issues with the repair. I do need more work and I will return.

I had a great experience at Agatha. The staff was knowledgeable, honest, and took the time to explain everything clearly. They diagnosed the issue quickly and had my car fixed faster. Prices were fair and transparent! It’s hard to find a mechanic you can trust, but I’ll definitely be coming back here for future repairs and maintenance. Highly recommend!
