Services
The Vault at Soneff's is a step above other vehicle storage facilities. Our "Vault" maintains temperature and humidity all year round ensuring the longest life possible for all the rubber plastic and wood in modern and classic vehicles. The Storage level at Soneff's is only accessible with an escort and you can be assured there's nobody touching or even looking at your car funny.
The Downtown Detail will drastically improve the overall appearance and long-term protection of your vehicle. We begin by carefully hand washing your car with industry-leading products, which ensures no additional scratching or left-over swirl marks. The doors, hood, trunk jambs, and wheel wells are washed in this process.
Soneff's Master Garage got its start in 1965 in Downtown Denver after John Soneff purchased what is now known as the Denver Tramway Building. SMG was originally a storage garage with a small mechanical area located on the main floor. Denver Urban Renewal decided it was best to tear down this historic building, forcing SMG to relocate to 1750 Welton Street.

Ervin and Jay were wonderful to work with and always kept me posted on the progress of my 1969 Firebird. The work was completed in a timely manner and reasonably priced. I would highly recommend this business to anyone in the Denver area. I would also like to add the professionalism of the front desk receptionist (I forgot her name). She was always very sweet and provided great customer service.

Had a really good experience with the service team. Went in for carb issues and a broken control arm bolt, as they discovered other shops miss steps they were really good about communicating and solving only what was needed. So many times other shops want to replace everything and run up a bill, never felt that way during my time. More so it was apparent they wanted my business over the long haul as they delivered my 66’ Vette in way better condition than when I dropped it off!
Don’t get caught up in the reviews about poor communication, they are just a busy shop and for a reason….They will

I want to thank you from the bottom of my heart!!! I roller skated in today behind a wheelchair desperate for help. I was greeted and taken care of right away. I couldn’t get a nut loose to tighten the chain on my bosses wheelchair. Not only did he loosen the nut, but he tightened the chain and actually listened to me when I spoke to him. Usually I… get treated like a stupid girl. While the guy was getting a tool, another worker asked if we had been taken care of. Very impressed w his confidence and knowledge and that he just did what needed to be done for us. With a smile too. I give

Jay took the time to show me a car he's got listed for sale, let me crawl around all over it, gave me the backstory, and also showed me around the shop. He's honest, funny, and very knowledgeable. If he has a car that you want to buy, you can rest assured he'll tell it to you straight.
Shop looks great, they specialize in older vehicles, and I'd trust them completely to do restoration work.
And - if you live in the neighborhood and need some help with something - I'm sure they'd do a good job. Just understand it's not just a regular repair shop - the place works on really valuable classic cars

Have a 1969 Corvette with an electrical problem that caused intermittent non-starting of the car. Took a few hours to trouble shoot and repair, but Soneff's solved the issue. Hats off to Irvin for this work. Also, Jason was able to remove a scratch on my Audi within 30 minutes. Did not expect him to be able to work on the scratch when I just stopped by earlier this week, but he fit it in. Very professional and courteous crew at Soneffs. Very customer-focused.

Serendipity at it's finest! I had a flat tire and was still 30 miles from home. I just happened upon Dave and his crew. Like literally, made a wrong turn and there they were! Not only were they kind a gracious, they also made me feel like it was no big deal and they were happy to help. I love the vibe in the garage ... it's like a 50's cafe for cars. Thank you guys so much! I really appreciate the kindness. I will pay it forward.

Where do I start with these guys!! I purchased a 1974 International Scout from a vintage auto place in Denver but live in Kentucky. Soneff's was recommended to me for an inspection of the vehicle and repairs. Jay went out and looked at it and then rushed it to his garage as I was flying out to drive it before shipping it home to KY. Once is was back at Soneff's is were the best experience I have ever had with a Garage started!! Dave was the head mechanic that took over, he took the time to advise me the things that needed done, the things that could be fixed later and always stayed in contact with

#1 car mechanic I have ever been to! 5-star customer service with extremely high quality repair work at a reasonable price. They have worked on my Ford Focus a couple of times to work on my exhaust and suspension system as well as basic maintenance. After every visit they step through the repairs that were made and they always put in better parts than were originally in the car. Dave and his team are the experts when it comes to automotive repair and I appreciate their honest communication!

Terrible customer service. I called 3 times over 2 days just to try and make an appointment. I was told Dave would call me right back. Never got the call back. If I get treated this way this way for something as simple as trying to make an appointment, I sure am glad I didn't leave my car here. Here's a pointer... If you are too busy, simply say "we cant take appointments right now"
Edit: Similar to my phone call the review response is 4 month later. The phone call resolved that you DO NOT service Audi when you clearly advertise that you do. I would suggest you don't waste peoples time.

These guys do great work. They were recommended to me by a highly experienced and respected classic car inspector and appraiser in the Denver metro area. I called Dave (the general manager) and spoke with him on the phone a couple times prior to any work being done. He knows and loves cars and it shows by spending any time talking with him. I took my 69 Mustang Mach 1 in for a new exhaust and detail work. They did a super job with the exhaust, and detail work, and threw in a new paint job for my rear window louver cover. The cover was faded and dingy, but they brought it back to life and made it

If I could give this place negative stars I would... I was in need of an oil change so I gave this place a try since the reviews were good... I dropped of my car and asked ballpark how much it would cost... the man at the counter, Dave, said it depends on how much oil they use but it's 12 bucks a quart. I said great and left, what he failed to tell me is it would be about 100 dollars in labor as well! when I pick up my car and get the bill I was in shock!!!! They charged me 200 dollars for an oil change!?!?! Now I'm used to 50 60 bucks and I knew this place would be more expensive since

Needed to get a check engine light checked out and it turned out to be a code that potentially had to do with a bad sensor. Dave explained to me that they usually try and clear the code first and drive it around to make sure that the problem repeats itself. It turned out that the light never came back on, Dave didn't charge me anything since this was my first time. I will definitely be back with any other car issues. Honest, friendly and very knowledgeable, thank you!

I took my challenger to these fine folks for some service and a detail. After 3 years, my baby was showing some significant scratches and I had accepted the fact they would be there forever. After the team was done with the chally, it looked like it just rolled off the showroom floor. Other places have detailed it before and nothing comes close to the attention that my car got at Soneff's. I will take my ride here for every service from now on. They are amazing! Don't go anywhere else if you live in a 2hr radius of Denver.

I don't normally write reviews but I had to make an exception for this crew. I showed up to work and had an awful leak and they let me bring in my car right away (they are only a few blocks from my office). Within an hour they were able to tell me what was going on (front axle leak) and an estimate for parts and labor. They ended up having to keep my car overnight and had my car ready early the next day. Dave even fixed up my grill for me at no additional cost, and my car was returned vacuumed and washed. Shannon at the front desk was also super nice! I'll be back there for sure :)

If money is no issue, this is the place for you! However, I think for most of us, we need a fair price for a fair job. They are arrogant, insulting and seemingly oblivious to the idea that they are working on cars, not solving the worlds problems. It doesn't have to be so dramatic and so expensive. A simple repair turns into a long drawn out process because they see an opportunity.

Seriously, top notch. Used these guys for a vehicle inspection since I'm in the Detroit area and not only were they super fast at getting it done, the report was super detailed. Super nice and professional, if I lived in the area I would definitely take my vehicles to them for everything.

Another nearby garage couldn't get me in for several days for an oil change and tuneup, but I drove by Soneff's and decided to take a chance. They sell and maintenance classic cars and I have a very ordinary Toyota, but Dustin and Jay (the managers) happily agreed to take care of it for me the same day. The price was more than I am used to paying for an oil change and tuneup, but the service and outcome was excellent - they topped off all liquids, replaced the air filter, did a complete diagnostic checkup, fixed a check-engine issue and removed the "maintenance required" indicator
