    Amazing shop, very clean and organized. Derrick will make sure you’re taken care of. He helped me deal with interlock system, specifically a life saver device, ironing out the issues the device itself is and dealing with customer service.

    This place is incredible - amazing work and great customer service. I will never go anywhere else. It’s always fun to see the high-end cars Derrick is working on every time I go. That’s when you know he’s the best of the best. Plus, I’m supporting a fellow Coloradan and local small business! He also does SmartStart Interlock installs and was of great support to a friend of mine. Even though he isn’t a therapist, obviously that isn’t his job, he still was very kind and patient with her while she was going thru a tough time in her life and listened to her story. Now she takes her car to him to be detailed too!

    Derrick has been my go-to guy for all things Smart Start! He's friendly, efficient and professional. Highly recommend if you're in looking for a knowledgeable individual to assist you with any and all ignition interlock needs. I had to get my device quickly transferred to a different vehicle a couple months ago. Derrick clearly walked me through the entire process and took care of everything in the span of just a few hours. He's open, honest and responsive. Thank you for all you do, Derrick!
