Editor's note: Contributor Ken Gross knows museums. He is the former executive director of the Petersen Automobile Museum and was guest curator for "Allure of the Automobile" at the High Museum of Art in Atlanta. He's developing the opening exhibit for LeMay--America's Car Museum in Tacoma, Wash., and he's creating an exhibit called "Speed: The Art of the Performance Car" at the Utah Museum of Art in Salt Lake City. Both exhibits open in June. We asked Gross to choose the country's five best automobile museums open to the public (not private collections). Here are his picks.

THE 5 BEST

Indianapolis Motor Speedway Hall of Fame Museum, Indianapolis

www.indianapolismotorspeedway.com

If you're into race cars, the Indy museum is simply the best, filled with trophies, memorabilia and 500-winning cars, plus a subterranean storage area.

Mullin Automobile Museum, Oxnard, Calif.

www.mullinautomotivemuseum.com

Peter Mullin's brilliant new museum is decorated like a 1930s Paris salon and is brimming with Bugattis and other delectable French pastries. It has limited hours, so check before you go.

National Automobile Museum, Reno, Nev.

www.automuseum.org

Featuring the cream of the old Bill Harrah hoard, this museum, with rarities such as the only pancake-engine Julian, is worth the out-of-the-way trip.

Nethercutt Collection at San Sylmar, Sylmar, Calif.

www.nethercuttcollection.org

The late J. B. Nethercutt amassed a fabulous classic-car collection. The museum is family-operated, and its comprehensive restoration shop (which has had many Pebble Beach Concours d'Elegance Best of Show winners) is second to none.

Petersen Automotive Museum, Los Angeles

www.petersen.org

Occupying an entire block on Los Angeles's Museum Row, the Petersen museum's ever-changing exhibits are thoughtful and timely. Its amazing dioramas bring cars to life.

RUNNERS-UP

Auburn Cord Duesenberg Automobile Museum, Auburn, Ind.

www.acdmuseum.org

Housed in the old Auburn Cord Duesenberg administration building, it's an art deco feast with rare prototypes and more.

Blackhawk Museum, Danville, Calif.

www.blackhawkauto.org

Rare classics and sports cars are gathered in a breathtaking setting. The three Alfa B.A.T. cars are like sparkling jewelry on black velvet.

Don Garlits Museum, Ocala, Fla.

www.garlits.com

Nearly all of "Big Daddy's" Swamp Rat dragsters are here, plus a lot of the cars he beat and a few that smoked him.

Museum of American Speed, Lincoln, Neb.

www.museumofamericanspeed.com

"Speedy" Bill Smith's lifetime collection of race cars, speed equipment and rare bits, from hopped-up Model Ts to Millers, are on display.

Simeone Foundation Automotive Museum, Philadelphia

http://simeonefoundation.org

You'll see Le Mans and Mille Miglia winners, early American racers, the long-lost Bonneville Cobra Daytona and weekend "start 'em up" demos.

The Henry Ford, Dearborn, Mich.

www.hfmgv.org

This destination was recently renovated with clever new electronic displays and favorites such as "Old 16" from the Vanderbilt Cup--and they're not all Fords.

Wally Parks NHRA Motorsports Museum, Pomona, Calif.

www.museum.nhra.com

Hot-rod heaven with lots of special events, the NHRA museum packs in every dragster you ever loved, along with trophies, memorabilia and more.

Walter P. Chrysler Museum, Auburn Hills, Mich.

www.wpchryslermuseum.org

Serious Mopar spoken here. See the '40s-era Newport and Thunderbolt concept cars, all of the 300s, plus former relatives such as Nash and Hudson.

BY INVITATION ONLY

Collier Collection, Naples, Fla.

www.revsinstitute.org

The museum houses nearly all of Briggs Cunningham's Cunninghams, significant Porsche racers and important Brass Era competition cars.

GM Heritage Collection, Warren, Mich.

www.gmheritagecenter.com

This is the General's attic. Many Firebirds and Motorama cars are here, nicely displayed, along with a great cross-section of other General Motors cars.

Jay Leno's Garage, Burbank, Calif.

www.jaylenosgarage.com

Go to the Web site for a peek, then bid at Pebble Beach for a private tour. Proceeds go to charity.
