    I highly recommend DMC for any service on your motorcycle! Mark is very knowledgeable, fast, and super customer friendly! I had to fix my bike fast because I needed to sell it, as moving abroad. He went out and beyond to get my old bike serviced, fast, and without overcharging. He even came and picked up the bike with his trailer. I would use DMC again, and again, if it wasn't that i'm moving abroad.

    Bam!

    Mark Duncan, the owner and main mechanic, has been my go to guy for everything motorcycle related for years now. His prices are so low I feel guilty, his work is beyond excellent and professional, and to top it off he is one of the nicest guys I've ever met. He is able to get all the parts, gear, and even accessories I've needed and his prices are much lower than the dealers. And seriously his tire prices installed can't be beat for brand new Michelin Pilots (or any tire I guess.) All in all, try him out once and you'll never need another mechanic for your street or dirt bike. Thanks Mark!!!!

    Great Job!

    See all

    I moved to Mira Mesa but I still take my bike here, since Mark is exceptionally trustworthy and down to earth.

    I really like finding owner/operators like Konstantin. Sounds cliche but when you own a business…read moreand interact directly with the customer and provide them a service, you're much more likely to care about what you're doing. I needed a front fork seal rebuild on my bike. I'd gone by a big local place up in Kearny Mesa (won't name) and dude was dismissive, like 'ah yeah a couple hours to pull the forks, a couple hours to rebuild...but we're a month out to get you in'. Acted like he didn't want my business and wouldn't even provide a number 'uh yeah like $130/hour times 4 hours, and yeah parts too'. Gel haired, flat brimmed, frosted tip 50 year old goofball. SD moto did a 24 hour turnaround. Yep, actually less than 24 hours. They preemptively got the parts (he paid for them) dropped bike off Friday, picked up Saturday. Beyond happy. I have a valve clearance coming up in a few thousand miles and I'll coming here. Also he's from Bulgaria , not Russia. Good guy! Edit Bulgaria NOT Belarus haha. Sorry!

    I was having my 2006 Kawasaki Zx10R serviced by a cycle shop closer to my area for years called…read more(motozone) on el cajon blvd but one day the main mechanic there named Roger told me my bike was too old for them to work on so I then stopped going there & I woiuld not recommend them to anyone. I then came across SD moto repair & found brother constantine. He is a 1 man worker but he does work at a fair price, & does it a good time frame & i have been taking my ZX10R to him for some years now for oil changes, tire changes, brake & master cylinder work, front & rear sprocket & chain replacement etcc.. he was even able to find me a replacement fairing for my Zx10R which are hard to find now because of my bikes age & he helped me today (9/13/25) properly fit a green rear seat cowl on my ZX10R that I bought on Ebay that is seen in this photo. I would reccomend him to any rider that needs their cycle serviced for fair pricing, good work & good turn around time. He also doesn't tell his customers "your cycle is too old" as the motozone mechanic told me years ago.

    To the Management Team (SERVICE DEPARTMENT) at DCH Honda of Mission Valley,…read more I am writing to share my experience during my visit on April 24, 2026, regarding an oil change for my Kia Carnival. While the visit began with significant challenges, it concluded with an impressive display of accountability that changed my entire outlook on your dealership. Areas for Operational Improvement I would like to offer constructive feedback regarding the intake process. My appointment was scheduled for 7:30 AM specifically to ensure timely service; however, upon arrival, the service lane lacked clear guidance. With three lanes filling up and service advisors moving between the garage and the vehicles, there was no defined queue management. This resulted in customers being served out of order, rendering the concept of an "appointment" feel ineffective. Furthermore, there was a breakdown in communication regarding the scope of my Lifetime Oil and Filter Change warranty. I had to provide my own documentation to confirm that chassis lubrication was included in my service contract. Additionally, despite scheduling the appointment in advance specifically to allow your team to order parts for my vehicle, the parts were not on-site when I arrived, resulting in an avoidable delay. Commendation for Simona Deloeste Despite these frustrations, I want to highlight the exceptional service provided by my advisor, Simona Deloeste. When the parts shortage was discovered, Simona could have easily deflected blame, but instead, she chose a path of radical honesty. She personally apologized and, impressively, took full accountability for the oversight. Her integrity and professionalism completely turned the experience around. She kept me informed throughout the wait and handled a difficult situation with such grace and maturity that she convinced me to maintain my lifetime service contract with your dealership rather than canceling it. Simona is a tremendous asset to DCH Honda of Mission Valley. Her ability to own a mistake and turn a frustrated customer into a loyal one is a rare skill. I requested to speak with a service manager during my visit to share this feedback and recognize Simona's performance, but I was unfortunately unable to connect with leadership. I hope this review reaches the appropriate management so that Simona can be recognized for her integrity and the high standard of service she upholds. I look forward to my next service visit and hope that the operational issues in the service lane are addressed to match the level of excellence Simona brings to your team every day.

    I had an absolutely awesome car-buying experience with Tony Maldonado! From start to finish, Tony…read morewas kind, patient, knowledgeable, and truly cared about making sure I found the right vehicle. He took the time to answer all my questions and provided excellent communication through text and email, which made the whole process so easy and stress-free. What really stood out was how upfront and transparent he was about pricing. He shared great information that helped me confidently decide which car was the best fit for me - no pressure, just honest guidance. Derek in the finance office was also a pleasure to work with. He made the paperwork process smooth, efficient, and surprisingly enjoyable! Overall, the entire experience was seamless and positive. If you're looking for a hassle-free, professional, and genuinely pleasant car-buying experience, I highly recommend working with Tony. I couldn't be happier!
