Museum Admission: $5.00 adults and children over 12. We pay your sales taxes, and your admission is good for the season, May to October. WHAT A DEAL! Best $5.00 you will ever spend!!!!

Our collection has continued to grow over the last 49 years. We are different than most museums. WE ACTUALLY BUILD OUR OWN CARS.

The museum is full of classic, antique, and custom vehicles, pedal cars, toys, oil and gas items, gas pumps, signs, memorabilia, all very nicely displayed. Very enjoyable for our guests!

Check out the RARE 1928 Marmon Victory 6 Coupe. 1 of only 6 known to still exist. 1921 Cadillac 8 cylinder Touring Car, 1914 Ford Model T C-Cab, 1931 Buick, and 1924 Chevy Touring Car, 31 Ford Roadster Pickup, and more.

See the row of beautiful classic and antique car engines, several real neon signs, and many other vintage signs. We still have a few classic motorcycles too. The mannequins throughout the museum are all decked out with correct vintage era clothing.

We have collected some very rare oil and gas memorabilia items, including vintage gas pumps, oil cans, signs etc.. Our collection is always changing, and evolving.

We call this place “Our Hobby That Got Out Of Control”. Cameras Are Allowed.

Walking through the museum, you will See History before your eyes. With many stories about the cars we’ve built and collected. The huge collection of vintage pedal vehicles, signs, photos, vintage toys, and much more are displayed throughout the buildings.

We also have a kids row of vintage gas powered cars on display. A sure hit with the young, and especially the young at heart, who remember the days of racing around in those vintage kids pedal and gas-powered cars. How about a 1958 Corvette kids gas powered car, or the Don Prudhome minidrag car. And, our favorite ” Uncle Doc Sidle”, who built a one of a kind chain saw powered race car with a custom formed modified Pontiac Hood, that sports a 49 Ford center grille. Uncle Doc phyisically formed the hood by sheer manpower using only his arms to correctly bend the hood. We sure miss Uncle Doc. He was a joy to have at the museum, and he always had some great stories to tell!

Our 2021-2023 additions include Bill’s 9 month total re-build of “THE JEWEL” A 1951 Chevy fixed window coupe- The former show car built in Rapid City in the early 60’s. “The Jewel” ended up completely stripped and sitting in a field 30 miles south of Rapid City. The car club members stopped at the museum after dragging the car out of the field. The plan was to cut off the front end and make a wall hanger, and the rear section a couch. Luckily, Bill convinced the club members to let him bring “The Jewel” back to show condition. “The Jewel” is true history and needed to be rebuilt. We were honored to be given a prime spot to display “The Jewel” in the 2023 Counts of The Cobblestone’s Car Show. What a great car show the Counts put on every February.

A good friend Mike Proios ( who is a great videographer, did a 12 video documentary on YouTube: (google) “Restoration of The Jewel”, Please: click on Mike’s LIKE BUTTON,& GIVE HIM A THUMBS UP! You can follow how “The Jewel” came back to the beauty she is now. The videos show people how these vintage cars were built back in the 50’s &60’s, the “Old Skool Way”. Several people helped us find parts, and donor cars, paint, upholstery etc. to rebuild “The Jewel” It was a lot of work, a lot of money. But, well worth it.

Bill’s 2022-2023 winter project was a restoration of a professionally built front engine Altered Drag car, that was retired decades ago.

A favorite with many is, our one of a kind 1956 Custom Mercury 2 door hardtop that Bill owned since the late 1960s. This Merc is totally a Fully customized long low custom, with a white pearl, and metal flake purple candy apple paint job. The 3 foot rear fender extentions, long crusier fender skirts and factory continental kit, make this a very long low 50’s era custom.

Bill spent a couple of years buiding his 1962 Dodge Dart 440 Magnum he rescued from the crusher north of Pierre SD. This car was in VERY rough condition, but now it shines, and is a star of its own. Also on display are a couple favorties. Complete ground up 1959 & 1960 Chevy Elcaminos.

When was the last time you saw a 1941 Lincoln Continental Coupe, or a 47 Lincoln Zephyr Convertible? There were only 1,250 of coupes, and 725 convertibles built. Both cars have been updated to cruise down the road in style. The RARE! 1940 White Horse milk truck, looks kind of like a Divco, but looks better even better since it has been restored and is on display. Peggy stored her huge hub cap collection in that White Horse. The engine sounds like a Harley Sportster. The company advertising says it gets 25 miles per gallon of gas. Better than nowdays! We also have the only known factory built on a 1925 Studebaker chassis RV. So much to see, so bring your camera, and capture all the vehicles, toys, pedal cars, vintage bicycles, gas pumps, signs, and so much memorabilia to look at, you just can not see it all in one visit.

BONUS FOR OUR VISITORS. When you pay your $5. admission, remember your admission is good for the whole season. You pay once a season, and you can return as many times as you would like May to October. Kids are free 12 and under, with an adult. Our admission has not increased SINCE 1997. (We have a good story why we haven’t raised the admission all these years.)

This is simply a best value deal in the Black Hills.

YES, we do sell some items and vehicles out of our museum collection. (PLUS, WE ARE ALWAYS LOOKING FOR CLASSIC VINTAGE VEHICLES TO BUY and Build.


REMEMBER: When you purchase a vehicle from us, we can help you with worldwide shipping. The cars/pickups/trucks in the Classic & Vintage Car Lot out front of the museum are for sale. We have titles for 99% of our vehicles, and again we offer assistance to shipping worldwide.

See you Soon! Bill and Peggy Napoli
