The Mach III H1 500 subsequently has been of great interest to collectors and historians of motorcycles, often appearing on lists of most significant motorcycles. The H1 was included in the Guggenheim Museum's 1999 "The Art of the Motorcycle" exhibition in New York, Chicago, Las Vegas, and Bilbao, Spain. Motorcycle historian Clement Salvadori noted in the Guggenheim's catalog that the H1, "was one of the least useful motorcycles available on the market" yet still sold very well because, in the heyday of American muscle cars where quarter mile times were paramount to the young male target buyer, it "could blow just about anything else off the road — for less than $1,000." Motorcycling author and journalist Roland Brown wrote that it could "beat almost anything away from the lights." Salvadori added that "Motorcycle lore has it that very few original owners of the Mach III survived." While older Baby boomers collected classic brands of the 1950s and 1960s like BSA, Norton and Triumph, a younger generation of motorcycle collectors was nostalgic for H1 Mach IIIs along with other bikes of the era, Honda CBs and CLs, Yamaha RD350s and Suzuki Hustlers.
