Riverside International Automobile Museum: The Selling Of A Museum

by Anonymous –

Back in 2006, Ray Magnon and his son, Doug Magnon, were two racing enthusiasts credited with founding the Riverside International Automotive Museum.

Originally, Doug being a Maserati collector, his goal was to have the largest collection of Maseratis in the U.S., but by 2006 he decided to have the museum be instead a history of California’s motor sports heritage specifically relating to the Riverside International Racetrack that was started in 1957 but which gave way to a shopping center later on.

The Museum opened to the public in December 2007 in one of the many office buildings owned by the family, whose development company is credited with developing much of the commercial infrastructure in downtown Riverside.

They also built a library of historic photos, videos, race programs and periodicals.

In March 2009, with Dan Gurney as the honoree, the museum hosted the first Legends of Riverside Film Festival and charity fund raiser. In addition to showcasing popular racing films, the annual event sponsored appearances by many famous racing legends of the past including in 2010 Carroll Shelby, 2011 Parnelli Jones, and 2012 Bobby Unser.

In 2015 Doug Magnon died at the young age of 55. It was hoped that the Museum could continue on but in June 2016 a letter was sent out by a Board member to a public information forum ( that said in part:

“the auctioning of the cars in the Riverside International Auto Museum (RIAM) has been approved by the board”.

The letter also said that “After multiple attempts to find a long term sponsor for the Riverside International Auto Museum the board of directors has decided to auction the cars and create a foundation in Doug Magnon’s name.”

“It was a difficult decision and we would like to see the cars go to Maserati enthusiasts so I’m hoping all of you can participate in the upcoming auctions.”

“The majority of the cars will be at the Auctions America event at Santa Monica the 25th and 26th of June.

The remainder of the cars will appear at RM Sotheby’s Monterey in August.”

There is a list of the cars in the Museum on Wikipedia, and that list is below, but it is far from complete. As of June 11th, 2016 the auction company photographer was at the Museum shooting cars destined for the Auctions America (a subsidiary of RM Sotheby’s) auction in Santa Monica.

There is no word on what will happen to the contents of the library or the film collection, or artwork on the walls.

  1. I’m glad that I had the chance to visit the museum. Two old loves: Riverside and Masers.

  2. Holy crap what a list.

  3. I am so sad to see this collection go. Many months ago I finally made my way out there and boy was was I amazed! Not only were the cars outstanding, but the staff was very friendly and eager to answer all of my questions. I am glad that I had the opportunity to go to the museum and see all of the cars close up!

    Maybe the Petersen or the San Diego automotive museums will step up and acquire some of the collection as well as the myriad Riverside Raceway memorabilia…….
