16 - 25 September


Housed in a former Santa Ana-based Hupmobile dealership, the Mitosinka Collection is the culmination of a lifetime of dedicated collecting and curation by Dennis Mitosinka, the noted vintage car appraiser, expert, enthusiast, and distinguished veteran. Offered entirely without reserve, the collection features over 30 vintage motor cars, primarily pre- and post-war American classics, as well as over 400 lots of automobilia, collectibles, and ephemera. The comprehensive collection shows great depth and breadth of the classic car world, comprising a diverse group of automobilia ranging from Route 66-era Petroliana to children’s pedal cars, automotive toys, mascots, rare car parts, automotive art and highly unusual and rare ephemera tied to all things automotive.

Please note that the collection is viewable in-person by appointment only, and transport of all lots will take place from the Santa Ana facility in Southern California.

Titles/Registration Documents

You will not receive your title for your car at the time of the sale. We manage the title transfer process on your behalf to ensure the car is free of liens and encumbrances. A $75.00 (USD) administration fee or its equivalent in local currency of the auction location ($65.00 (USD) in the State of California) will be assessed per motor car(s) purchased by an individual Buyer, however this fee will not apply to nostalgia lot(s). You can expect your title to be couriered to you within 20 business days post-sale, at which time you can register the car at its final destination. If a lot(s) is rendered “Title in Transit,” it is unlikely that the Buyers will receive the title in the mail within 20 business days following the auction; however, RM will work to provide the titles to the Buyer as soon as possible.
