Why Mount Carroll Trusts Premier
The results speak for themselves
Every vehicle we touch gets treated like it is our own. From deep interior cleaning to flawless paint correction and long-lasting ceramic coatings, our work reflects real craftsmanship. We use industry-leading tools, techniques and products, and the finish shows it every time.
A shop you will actually want to walk into
A detailing experience should feel as premium as the result. Our shop is clean, professional and welcoming. Whether you are bringing in a daily driver, a luxury car or a weekend toy, you get straight communication from the first phone call to the moment you pick it up.
We do it right the first time
Car owners who care about quality come to us because they know the job gets done properly the first time. Attention to detail is not a slogan here. It is the reason people drive in from across Carroll County and further out.
Protection, not just shine
Our ceramic coatings and paint protection are more than cosmetic. They defend your investment. We partner with Feynlab and stay current with coating technology so you get real durability, not a gloss that fades in three months.
Small-town integrity, big-time results
Based in Mount Carroll, we bring honesty, hard work and reputation into every job we take on. No shortcuts, no rushed work, just high-quality results that hold up.
Rated 5.0 Across 102 Google Reviews
We have protected more than a thousand vehicles across Northwestern Illinois, and we have never dropped below five stars. Here is what customers say.
Every Coating Includes the Premier Care Club
A ceramic coating is not something you apply once and forget about. It needs the right maintenance to keep beading water, staying glossy and protecting the surface underneath.
That is why every coating we install includes automatic enrolment in the Premier Care Club. It is not an add-on and it is not a paid membership. If you get your coating done here, you are in it.
From 330 Detailing to Premier Auto Studio
Joey Promenschenkel started this business in 2020 out of a home garage under the name 330 Detailing. It was a side hustle built on a real passion for cars, and it did not stay small for long. In 2023 we moved into our current shop at 751 West Commercial Street, and in July 2025 we rebranded to Premier Auto Studio.
Same owner. Same standards. Same shop. If you knew us as 330 Detailing, it is still us.
