Ridler Award

The Detroit Autorama Ridler Award is Presented By Meguiar’s


2024 Ridler Award Winner

David Maxwell – Pennsylvania – 1953 Corvette Custom “TwelveAir”

The 2024 Don Ridler Memorial Award Winner

Just qualifying for the top award at the Detroit Autorama is hard enough: only eight vehicles are picked for the first stage after having impressed the judges with their creativity and quality craftmanship. Those top eight cars, collectively known as the BASF Great 8, then compete against each other for the Don Ridler Memorial Award presented by Meguiar’s.

Named for the first professional promoter of the Detroit Autorama, the Ridler Award is among the highest honors in the show car world and has been awarded at each Detroit show Autorama since 1964. The Ridler winner exemplifies the highest level of fabrication and design coupled with an extreme attention to detail.

This year the Don Ridler Memorial Award was awarded to David Maxwell for his “TwelveAir”, a one-off, hand-fabricated, aluminum-bodied coupe whose initial design was inspired by the 1953 Corvette Corvair Motorama concept car with its fastback roof and trunk. Dave Kindig’s Kindig-It Design in Salt Lake City hid the project from the public (one of the “Ridler Rules”) for the past 5 years as they scratch built this entire car.

The engine, custom built by Australia-based Race Cast Engineering, is an all-aluminum 9.2-liter (561cid) V12 LS (actually made from two modified LS blocks mated together) that connects to a C7’s 8L90E eight-speed automatic transmission. JS Custom Interiors stretched a Sienna leather over the 3D-printed dash and console, and the floor mats were machined out of aluminum, sanded, painted black, trimmed with hand-formed stainless steel, and finally finished with a leather backing.



Since its debut at the 1964 Detroit Autorama, the Ridler is one of the country’s most prestigious automotive awards that concerns custom and hot rod car owners and builders. Given annually to an exceptional vehicle that falls under strict “never been shown before” guidelines, the folks who win this prize become members of a very elite group.


About Don Ridler

Don Ridler was a man with a very competitive spirit, excelling in athletics in high school and later at Michigan State University. His many achievements eventually landed him in the Michigan Sports Hall of Fame. After college, Don coached Lawrence Tech’s basketball team and served as Athletic Director in the 40’s. After games, Don would contract entertainment such as Tommy Dorsey and Glen Miller for dances. During this period, Don also produced the Michigan State Fair Grandstand shows and handled public relations for horse tracks in the Detroit area. In the 1950’s, the producers of Autorama decided they needed promotional help to take the event to the next level, and turned to Don Ridler. With the help of Don’s creativity and professionalism, car enthusiasts flocked to the Coliseum at the Michigan State Fairgrounds to see some of the wildest hot rods that cruised the streets of the Motor City, and were entertained by acts such as Little AnthonyThe Imperials, and The Big Bopper. Don Ridler passed away in 1963 at the age of 54. It was immediately decided that an award be created to honor his memory. Don’s forté had always been his creativity. Therefore, it was decided that the award would honor individuals who are equally creative in building cars. The award, geared to honor new creations, is only eligible to cars shown for the first time.


Don Ridler was the first professional promoter hired by the MHRA to assist them with the fledgling Autorama in the Fifties. With Don’s creativity and professional approach in promoting, Autorama was able to grow tremendously and eventually move to its present home at Cobo Center in 1961. In 1963, Autorama decided to honor Don Ridler, who had prematurely passed away, with an award given in his name.

Originally, the award was given to the Best Vehicle shown for the first time. Over the last fifty plus years, the award has evolved to better conform to new ideas, changing designs and concepts. Today it emphasizes creativity, engineering and quality workmanship. Anyone building a vehicle for Ridler competition should post these words on their garage wall. The vehicle that best represents those three areas will win the Ridler Award Sponsored by Meguiar’s.

In addition to those judging guidelines, there are a few hard and fast rules, with no exceptions:

The vehicle must make its first public showing at the Detroit Autorama. Showing the vehicle (or any unique part of the entry, i.e. frame, engine or body) at any indoor or outdoor show will make it ineligible for contention. Please feel free to contact us with questions about eligibility.

Except as otherwise set forth below, no photos or comments of the contending vehicle are to be posted on Facebook, Twitter, Instagram, Youtube, Tik Tok, LinkedIn, MySpace or any other social media website or internet comment board or blog or sent via text message or email. Friends, family and other third parties with access to the vehicle must be advised of the above statement and Meguiar’s Ridler Award Qualifications.

Photos, artist renderings or videos showing the vehicle in a completed state or in finish color are not allowed, and will result in disqualification. All decisions concerning prior exposure and eligibility for the Ridler Award will be determined by the Michigan Hot Rod Association and Championship Auto Shows, Inc.

The vehicle must prove to be operable. It must start, stop, move forward and backward under its own power, turn left and right and stop using the brake pedal, and be driven to its display spot on the floor. Keep in mind that these guidelines are minimum qualifiers. Operational functionality is something the judges will look at.

Once the final Ridler Contenders have been determined, the field will be narrowed to eight finalists, which will be referred to as the BASF Great 8 Finalists. Because of the number of entries contending, the process of elimination will begin on Thursday evening after move-in has been completed. Entries do not need to be 100% set-up, but should be at a state that they can be evaluated fairly. The BASF Great 8 Finalists are announced Friday morning and introduced at the Ridler’s Ball on Friday evening.

If an entry is selected as a BASF Great 8 Ridler Finalist, the car will not be eligible for any Autorama awards involving class judging and special awards. Owners and builders should also keep in mind that they will be asked during the weekend to open and close their vehicle to be checked for fit and finish, and to make sure everything is operational.

There will be a BASF Great 8 Ridler Contenders’ meeting for the builders and owners. This meeting is an opportunity to meet the other finalists, the judging staff and ask questions on how your car will be judged.

Meguiar’s sponsors the Ridler Award, the most prestigious award in the indoor custom car show industry, and presents the Ridler Award winner with a prize of $10,000 at this year’s Detroit Autorama.
