    I had a really great experience at this shop and honestly can't recommend them enough. A few weeks…read moreago, my catalytic converter was stolen, and I had it replaced at another shop. After that repair, my check engine light suddenly came on--even though it wasn't on before. The first shop told me it was a problem with the mass air flow sensor and tried to charge me to fix it, which didn't feel right to me. So I decided to come here for a second opinion, and I'm really glad I did. The mechanic took the time to properly diagnose the issue and walked me through everything step by step. Within about an hour, he figured out that it wasn't the air flow sensor at all--it was just a blown fuse. That alone saved me a lot of money and potentially from being overcharged elsewhere. What really stood out was the honesty and communication. He explained clearly what went wrong, didn't try to upsell anything, and made sure I understood the situation. On top of that, he even aired up my tires for free, which was a nice touch. Fast, honest, and affordable service like this is hard to find. I'll definitely be coming back and recommending this shop to others.

    Amazing service, quick (10-15min), affordable, friendly staff, professional - highly recommend! I…read morebought a lightly used tired that looked practically new for half the price out the door of what I was quoted at American tires. I had a concern that maybe the price was so good because they were using tires that were patched or something but nothing could be further from the truth! They shared were they source their tires from and rest assured you're getting a great deal for sometimes practically new tires. These guys and girls are the real deal. They have earned a life time customer and my trust to send my friends and family in the future!

    I got a few quotes before deciding to bring my 2014 Prius Plug-in here, and I'm really glad I did…read more They weren't the cheapest and they weren't the most expensive, but I felt like they charged what they needed to in order to get the job done I had no idea they even worked on hybrids because I never saw that mentioned anywhere, and I think more people should know. They took the time to explain the repair, confirmed the diagnostic code, and even pointed out a few things I should do to help my Prius last longer. They noticed my hybrid battery cooling fan was missing after I told them I just had it "replaced" at another shop. That's the kind of information you don't usually get from a repair shop. They ended up not needing to drop the subframe, so they adjusted the labor instead of charging me for work they didn't have to do. It still took the amount of time they said it was going to take, but still discounted me a little bit which I thought was cool. I also had them do an oil change while it was there, and even that was less expensive than what I normally pay at places like Jiffy Lube or Valvoline. If you own a Prius or any hybrid, I'd definitely recommend checking them out. More than anything, I left feeling like they genuinely know these cars and took the time to educate me, not just fix it. I'll definitely be bringing my Prius back if I ever need anything else.

I got a second opinion and found out a tensioner in the timing chain had broke, and that was it, they rebuilt the timing system and I'm back on the road for less than $2000. I wouldn't trust them to change my oil.
