I never once felt talked down to or rushed, which can honestly be rare in automotive situations. What impressed me most was how clearly they explained everything. They took the time to walk me through what was going on, what my options were, and what actually needed to be done (without trying to upsell anything unnecessary). That level of transparency builds immediate trust. They got me in and out exactly when they said they would, and the pricing was more than fair for the quality of service. If you're someone who wants to feel confident you're being treated honestly and respectfully--this is the place. I'll absolutely be coming back and recommending them to others.

If I lived down the street from these guys, I'd be going to them ALL the time, I could also tell they were popular from the number of people and calls they were getting while I sat in the shop for just about a half-hour. Obviously, I'd highly recommend these guys; they're definitely an asset for their community and real pros, too.

Went here to get suspension work done on my Tesla. Overall the vibe was friendly and the mechanic…read morethey had look at my car seemed to be top notch. He was the reason I wanted to get the suspension serviced here as his explanation of what I needed done showed his mastery of his craft. However after taking the car to Tesla to get a 2nd opinion I discovered that this shop (not the tech) was trying to charge me literally a 200% markup on the parts to do the repair. Crazy right!!! The genuine Tesla parts for the repair were $209 and these guys quoted those same parts out to $614 (I sent him the estimate from Tesla with the exact cost of the parts). Unfortunately for me Tesla wouldn't work on the car because of an aftermarket body kit the previous owner had installed. I really liked the mechanic at this shop, so I went back to this shop with the intention to move forward even though their cost was literally 56% more ($1,635 vs $2,555) then Tesla for the same work (because of the price gouging on the parts). Then when I asked about it before my approval to move forward the manager got snarky and said how would you expect us to stay in business if we don't markup the parts. I said and I quote "I get a markup on the parts and your high hourly rate for the labor on the work but not a 200% markup on the parts." The guy gave an excuse about the software they use but was unwilling to budge on the price gouging. I literally said why don't you let me buy the parts directly from Tesla and you can still mark them up 25% and he still said no. I was completely professional throughout the conversation, but obviously would not pay a 200% markup on parts on top of the already top of market labor they charge. After the conversation he texted me back and we agreed to not move forward. I only leave this review to warn others. It's a bad business practice to over charge people like that and so I just wanted to give people my story warning them to watch out and be careful before doing any work here. Update: this slime ball's disclosure of all the information I gave his manager, Steve, in good faith is abhorrent. Everything he mentioned on the car was told to them right up front as I told it to the manager, Steve, in person and this clown is repeating word for word what I told his manager. I was cool with this at first but this guy is a complete scum bag now using my own words and lying about it. Anyways besides being a scum bag, no effort at all was made regarding the parts and this shops 200% markup. I literally told the guy running the shop I would buy the parts myself and let them mark it up 25% and still the answer was a quick no. Everything I said was honest and accurate and don't appreciate this guy claiming transparency when his long shpeel was essentially just a my own words complaining about the car I bought and his shops poor excuse for price gauging. They could have done the job without gauging me on the price given I had the option to buy the parts myself. Not cool at all the response from this guy and his piss poor excuse for attempting to rip me off.

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
