Aftermarket accessories and trim for your car or truck

Who We Are ...


          Auto Trim Design of Montana was started by Doug Smith and has been serving Montana for over 35 years. It was originally known as

Trim-Line/3m, later changing our name to Auto Trim Design, and belonging to the Auto Trim Design Network, consisting of over 350 members nationwide.


          In 2000, the network came to be called the ATD Group, and recently changed its name to Restylers International, of which Doug Smith serves as 1 of 8 on the board of directors. Restylers International is comprised of over 450 members internationally serving the restyling industry. A recent alliance with AAG (American Automotive Group) has swelled membership to over 650.


          Since its inception, Auto Trim Design has been serving the local new car dealers as well as the general public from its retail store outlets. Our products include car and truck accessories, window tinting, electronic products, and custom signs and graphics. One can either purchase the products from us, or have them professionally installed by our quality installers.


          For 35 years, we have served our customers with the utmost of care and experience to insure customer satisfaction at its highest level. That's why so many of our loyal customers return again and again.


           Not only that, we continue to educate ourselves by frequently attending trade shows, national conferences, and seminars to keep ourselves up to date on market trends and products in order to continue serving our customers on the leading edge of our field of expertise.
