Now in its 32nd year, Dana Mecum’s Original Spring Classic auction is slated to make its grand annual return to the Indiana State Fairgrounds in Indianapolis this May 14-19. Considered a “bucket-list” must for enthusiasts across the U.S. and from dozens of foreign countries, the Indy auction today boasts a 2,000-car lineup spread out over six auction days, and this year’s roster is among the most significant and compelling to come out of the event’s 32-year history.

Main attraction consignments include four Shelby Cobras from The Steven Juliano Estate Collection, all of which exist as best-of-breed examples. Likely the most authentic and correct Cobras in the world, the selection includes a 1967 427 S/C Roadster (Lot F128), a 1964 289 Roadster (Lot F132), a 1966 427 Roadster (Lot F136) and a 1965 Factory Stage III 289 Dragonsnake (Lot F140). Other offerings from the collection include a group of cars used in Plymouth’s Rapid Transit System Caravan traveling road show, a one-of-11 1963 Cheetah Race Car (Lot F138) and nearly 2,000 items of Road Art® primarily composed of Chrysler, Dodge and Plymouth promotional items and awards from the 1960s and 1970s. A selection of the Road Art® will be offered via Mecum’s all-new timed online auction platform at ontime.mecum.com.

Famed restoration artists Amos and Justin Minter will offer a selection of cars at the Indy auction as well, including nine desirable F-Code 1957 Ford Thunderbirds, two E-Code versions and more. A selection of iconic American muscle cars from the Canada-based Zandee Collection will also join the Indy lineup, as will an array of classic ‘50s favorites from The Vintage Dream Car Collection; and the well-known Waterford Collection will return to the Indy stage this May with another assemblage of investment-grade Shelbys and Mustangs.

Other featured offerings slated to cross the Mecum auction block include a well-documented 1970 Plymouth Hemi Cuda Convertible (Lot F120), the only 1970 Dodge Hemi Challenger R/T factory-equipped with a sunroof (Lot F143), a 1971 440 Six Pack Plymouth Cuda Convertible (Lot F142), a 1967 Chevrolet Yenko Camaro (Lot S127) and a 2015 Porsche 918 Spyder Weissach (Lot S155) with 999 miles, to name just a few.
