    Amazing and friendly service! I was in and out in about 20 minutes. The whole process was quick, easy, and hassle-free. They were professional, efficient, and made getting my smog check as convenient as possible. If you need a smog inspection in Novato, I highly recommend Hamilton Smog!

    Called the shop on a Saturday to ask about Smog checks for our 2 vehicles and he invited us to come on in. We met Carlos who was friendly and professional - said we've be done in about 35 minutes. We did a short walk about downtown Novato and returned to find both cars were done! E-certificate send off to the DMV and receipts ready - prices were as good or better than other providers (and without having to have a coupon). I appreciated the prompt, friendly service and will definitely recommend Carols and Hamiltons Smog without reservation.

    Probably the best SMOG experience I've ever had (Even though my car failed the first time). I stopped by the first time and surprisingly they weren't busy. I talked to the owner, Carlos and had a good feeling about it so I asked him to proceed with a SMOG check. I wanted to kinda feel it out because 1, some SMOG technicians are complete pricks (More on ths later). Not so with Carlos. 2, my car had a special consideration and just by having a 5 minute conversation you can tell he knew exactly what he was doing. So after testing the first time it did fail even showing no codes/DTC's :-( However after talking through it he educated me about the quirks of my type of motor. I took his feedback and went through the processes he outlined. I came back a few weeks later and man, was it busy. I asked if I could come back later and he directed me to give him a call an hour before close. I did so, came back, threw it on the computer and it passed! One of the other great points about Hamilton's and Carlos is that the price is pretty fair. It's an honest business and Carlos is a straight shooter. To qualify my earlier statement, I've owned performance cars my whole life. Many techs will automatically fail you on the smallest little thing. In my case I have an EO/CARB approved performance kit on my car with documentation displayed. Carlos popped the hood, I described the kit and he went about doing his business. He was very professional and did his due diligence. Upon failing the first time we had a lengthy conversation as described above. Just due to the time and effort he put into the overall interaction I will definitely bring all my business here.

    I was able to drive in without an appointment and only had to wait 15 minutes for a smog check. Friendly staff as well!

    Efficient, fast, convenient, professional, clean, reasonably priced, and polite - what more could you want from a smog check company?

    I recently set out on what felt like a daunting mission: finding the perfect manual transmission…read moretruck for my husband as a complete surprise. Having never navigated the car-buying process alone--without my dad or husband's guidance--I visited and contacted numerous dealerships. From the very first interaction, it was clear this one stood head and shoulders above the rest. Their professionalism, warmth, and genuine commitment to customer happiness made what could have been stressful feel seamless and joyful. Hugh in sales deserves every bit of praise I can offer. He was extraordinarily patient as I walked him through my vision for this surprise gift, answering every question with clarity and never once making me feel like a novice. What truly set him apart was how far he went to ensure the moment would be perfect. He personally drove the truck to a friend's house and arrived with a huge red bow tied on the hood--turning a simple delivery into something magical. His thoughtfulness and "above-and-beyond" spirit made the entire surprise a resounding success, and I will never forget that kindness. Mike, the manager, brought the same level of positive energy and efficiency. Friendly and solution-oriented, he quickly coordinated all the custom upgrades I wanted, making sure every detail aligned with my husband's tastes and our family's needs. In finance, Josh was equally impressive. He explained every option with honesty and patience, never rushing me and always prioritizing what we truly needed rather than what might look best on paper. His knowledge and straightforward approach gave me complete confidence in my decisions. This dealership isn't just about selling vehicles--it's about creating meaningful experiences and building trust. In a world where car buying can often feel transactional, their team made it personal, caring, and even fun. I left feeling genuinely cared for, and my husband's reaction when he saw his truck made every moment worth it. If you're looking for a truck (or any vehicle) and want to work with people who truly listen and go the extra mile, I cannot recommend this dealership highly enough. Five stars, without hesitation. Thank you, Hugh, Mike, Josh, and the entire team--you've earned a customer for life!

    This Toyota used to be okay but something happened in the last year. I tried to schedule an…read moreappointment to take my car in for servicing and it was ridiculously difficult. I left multiple voicemails and nobody got back. Finally, I got someone on the phone who didn't really put a lot of effort into helping me. She couldn't take the time to look up my vehicle in their system and tell me what was covered with this service plan based on my mileage. Nevermind that i have been taking my car there for years so that info should be easily accessible. Instead, she transferred me to voicemail. I left multiple voicemails, never got a single call back. Finally called and asked to speak to a supervisor, only to get yet another voicemail box. This one was completely full so I was unable to leave a voicemail. WOW. This is the worse service I have ever received at any Toyota and I have been a Toyota customer for decades. I ended up going to Hansel in Petaluma which was a great experience. Even though I had never been there and I wasn't in their computer, they were able to tell me what was included before i came in. They told me how much it would cost and scheduled me in the next day. Everybody was super nice and it's an overall much nicer dealership. I recommend anyone reading this ditch Novato Toyota and go to Hansel in Petaluma!
