In addition to automotive detailing, Brian provides honest diagnostic work and mechanical repair labor. All automotive parts must be paid for in advance after you approve the estimate, before parts are ordered. As a small shop already investing in Subaru projects, I can't carry customers' parts costs. Brian confirms the repair scope, labor estimate, and timing before work begins. Explore our Subaru repair project photos in the gallery or contact the shop for an estimate.

Brian Gillette grew up in Miles City and began detailing at 17 at Carnu Detail in Billings, then owned by Rimrock Auto Group. His work earned him a promotion to train as—and later become—Subaru's lot manager in Billings. After starting his own business, he continued his education with an Automotive Technologies certificate from Miles Community College. More than a decade of hands-on experience, hard-earned lessons, and a commitment to fair treatment shape the work at Flawless Auto Spa today.
Brian also offers honest small mechanical repairs and specialized Subaru work. See our homepage add-ons panel or full Pricing section for repair labor rates, oil changes, and parts prepayment policy.
Brian and his wife, Michela, are proud to be part of the Miles City community. Michela helps with many aspects of Flawless Auto Spa while also teaching at CCDHS here in Miles City and coaching softball and cross country, among her many other commitments.

For our flagship Full Spa Combo, plan for at least the entire booked day—even if dropped off the prior evening—and a possible additional night stay. Handoff and pickup times are coordinated directly with Brian.
