At Sill-TerHar Mazda, We Make YOU Our First Priority


Your satisfaction is at the top of our list of goals. This is why our Mazda dealership serving Denver, Lakewood, Longmont and Aurora carries new 2020-2021 and used Mazda models. Renowned for their design language, enduring quality and value, vehicles such as the Mazda3, MX-5 Miata, Mazda CX-5, Mazda CX-9, Mazda MX-5 Miata and Mazda6 are proven crowd pleasers.

What's more, our commitment to your satisfaction transcends the day you sign for your car loan or Mazda lease. Take our service center, for example. Known for consistent, do-it-right-the-first-time service, it's here for all of your routine maintenance and car repair needs.

In understanding that some people like to take auto service and repair into their own hands, we also have a parts store where you'll find everything from Mazda brakes to oil filters, rotors to axles. If you're a novice mechanic, our knowledgeable staff will even help you figure out which part you need.

What do you say, isn't it time you put yourself first?

If you answer yes, come to Sill-TerHar Mazda for all of your automotive needs. You'll quickly see that we aim to please. We are located at 1480 West 1st Avenue in Broomfield, CO.
