He charged me to install 5 shocks he only installed 4. He ask to put in a EFI it never worked I found the fuel lines sitting on the exhaust. We replace water pump it leaks. He got into the transmission it leaks at the gasket. He installed linkage to trans it down shifts on its own. He did the brakes driver side locks up while the others do nothing. He installed a old EFI USED The wired he installed all loose sitting on intake. I had my bronco covered cause the seats were in mint condition. He left it out with out it covered the seats are ruined. I went back over and over trying to pick ok up when he called to say it was ready but every time I went it wasn't at all. I paid for all the work upon completion until the EFI. He demanded money order or cash. He said if I put it in a money order to put it in his mom's name. He said he would not release my bronco unless I paid I. That way even thought I paid cash for everything and even paid cash for the EFI unit and told him I could pay cash for balance. I ended up involving the police. I had them on site to help scare him so I could pay it off and get my Bronco.

He said he would give me a huge discount if I gave him cash. I gave him $1,700. I took my car back to him 7 times in the last 6 months. Several times he kept it for 2 or 3 weeks with the promise that it would ve done tomorrow. Each time I picked it up he said it was fixed. (It was not) The last time I took it to him 3 weeks ago. He asked me to bring it in the morning, but when I got there he was not there. 3 more times that day he broke appointments with me. I told him I wanted my money back. He swore at me and told me to get out or he would call the police. I went the next day and again he screamed at me to get out of his shop or he would have me arrested. I am a widow and money is not easy to come by. I have since had it fixed and the parts he said he replaced had not been replaced. Super bad business man

I recently had the clutch begin to make noises so I had it towed to Hands on Auto Tech for a…read morediagnosis.. There was a problem with the communication surrounding the tow transfer so I started my experience with Hands on Auto Tech with some trepidation. Tom handled the situation and we moved onto the real problem with my truck. The diagnosis was the clutch so I approved the repair and waited a few days for the parts to arrive and the repair to proceed. After the clutch was replaced another problem with the operation of the clutch was discovered so I agreed to the additional repair and another day for repair. After a week I was reunited with my truck. The repair was costly, lengthy and unexpected but coming out the other side of this experience I learned a couple of lessons. 1. If you have your vehicle towed to a shop follow the tow truck to the shop and verify the transfer. 2. Communication and follow up throughout the repair are key Tom was great to deal with and I feel that he was honest with me about the repairs needed and the cost of those repairs. Having recently moved to the area I feel my vehicle maintenance and repair needs can be checked off the list. I can recommend Hands on Auto Tech to anyone needing an honest repair facility and Tom as a good guy to deal with.

Got it back after a few short days and will be getting some further work done as time goes on. This truck had belonged to my former landlord whereupon his daughter sold it to me as the old boy had gone to a retirement facility. In his later years maintenance and repairs had been let go but being sturdy and strong running, I bought it and am slowly bringing it up to snuff and it is good in the event I should need to do any long distance traveling with it. . Attended the new shop opening, located just off I-25 and Colorado route 66, where I met Mr. Maggio's family and some of the other customers who call Hands On Autotech their home for vehicle repair and servicing. I first went there based on the recommendation of the Martino troubleshooter show on 630 KHOW AM radio; 10 AM - 2PM, M-F. My opinion is that Tom's shop takes something of a scientific approach to vehicle repair and will go more in depth with an analyses than another shop I had been to for an issue with my '99 Tahoe. As an EV owner himself I gather that Tom is up on the current tech, perhaps more than some other places who would have men of my age (68) from the "dinosaur era" of automotive tech working at their shops.

Horrible!!! Used…read morethem for possibly 5 yrs servicing 4 different cars. They are good at general mechanics. But complex, No!!! Here are 4 situations that made me see new mechanics: 1.) 8 yrs ago, I overheated the engine and cracked the block on my 1984 Landcruiser. They rebuilt the engine, for about $8,000.00. While in the process, Tim claimed the bottom did not need rebuilding. So they closed up the engine. But I was now burning oil. 2 Qts/ 500 miles. They refused to fix the problem. Tim blamed that I told them to not rebuild the bottom end of the engine. (Ask him about it!) 2.) Just last month, Feb 2026, the catalytic converter on my Landcruiser started to fail. They installed that about 6yrs ago, for about $1,200.00. 3.) 2006 V70,Volvo had a small radiator leak. I brought it in each of the 2 times the Low Level light went on. Each time, they could not find the leak. The 3rd time I brought it in was because the radiator blew and the car overheated. I told them to check that I had not cracked the block before repairing the radiator. They repaired the radiator first., about $1,200.00. Then determined the block was cracked. (Rebuild by Swedish Motors was $6,000.00.) 4.) 2009 S80 Volvo. Had them look at this car to see if it was safe to buy, for my 17yr old daughter. The results of their inspection was "it's in great shape". 1 yr later the transmission went. And I found out that this was the one yr Volvo used a Ford impala transmission. No replacement parts, used or rebuilt transmissions were available, per Swedish Motors. I had to scrap the car. When I confronted Tim and Tyler that they should have known this about this model they said that was something I should have known about the car. NOTE: These guys do not deserve those big stickers on their front window that say Toyota and Volvo. Call me .... Dave Longmont, Co 720-745-9460

These guys have…read morebuilt a solid reputation for their honesty and integrity, and also their KNOWLEDGE AND ABILITY to work on today's computerized, fuel injected vehicles. For this reason, they will always get my business unless it is absolutely necessary to go to the Ford dealer (in which case I only recommend Sil-Terhar in Broomfield). My F150 recently needed a new battery, and at the time the old one died for the last time, my heater stopped working. They could have told me that I needed a new heater core, new heat/ac blender actuator, or blender door (all ranging from $250-$400 in repairs). Instead, they took the time to troubleshoot, and only needed to reset the HVAC module - less than an hour's worth of labor and no parts. What's more, they contacted me mid-day (same day) to let me know that it was ready to be picked up. Many other garages would have torn my dashboard apart and gone the wrong way with troubleshooting this. I don't have enough words to express my gratitude for their professionalism!

He was even helpful when I went back to the previous shop to get them to reimburse me for my expenses (which they did). Highly recommend them as an ethical shop, not taking advantage of customer with no mechanic knowledge!

After receiving an outrageous $8,500 estimate from a Denver mechanic while stranded on Mother's Day, I had my 2017 VW Tiguan towed to Carbon Valley. Their inspection was detailed, honest, and thorough. They discovered the noise I heard was caused by a rock stuck in the driveshaft -- not a broken turbo as I was told. They removed the debris, topped off fluids, checked all systems, and only found that the brakes needed replacement -- which they completed for $1,270. This shop treated me with respect, transparency, and integrity. I'm a senior woman, and I felt completely at ease with their service. I now know I can trust them with any future repairs.
