By Wednesday, May 13, Mecum Indy should already feel like a place where ordinary expectations start to loosen. The Indiana State Fairgrounds will be full of blue-chip classics, high-horsepower icons, and the kinds of collector cars people came specifically hoping to see. Then there are the convertibles, which bring a different kind of energy altogether.
Open-top cars do not just add style to an auction lineup. They add atmosphere. They invite you to imagine the road ahead, the weather, the soundtrack, and the kind of drive that matters more because there is nothing between the cabin and the sky. At a sale this large, that kind of emotional pull can make certain cars feel more memorable than machines with twice the horsepower.
This group works especially well because each one approaches open-air motoring from a different angle. One is tied to Mustang anniversary history. One carries Chevrolet’s rear-engine curiosity. One turns retro truck styling into a promotional oddity with real Indianapolis flavor. Corvette brings familiar American sports-car energy, Bentley delivers handcrafted grandeur, and Pontiac closes the set with one of its most vivid late-performance-era convertibles.
Together, they give Wednesday a bright and distinctive personality. These are the open-air standouts everyone will be watching at Mecum Indy.
1984 Ford Mustang 20th Anniversary Convertible
The 1984 Ford Mustang 20th Anniversary Convertible arrives with exactly the kind of backstory that makes collectors stop and look closer. Mecum lists Lot W57 as one of only 104 produced with the turbocharged 2.3L/145 HP inline-four and a 5-speed manual, and it also shows just 4,297 miles. That gives the car real intrigue before the conversation even turns to condition.
The anniversary identity already makes it special, but the unusual powertrain is what gives it extra character. This is a Fox-body Mustang that sits slightly outside the usual V8 conversation, and that difference is a big part of its appeal. At Indy, it should connect with buyers who like their Mustang history a little rarer, a little quirkier, and a little less predictable than usual.
1966 Chevrolet Corvair Monza Convertible
A 1966 Chevrolet Corvair Monza Convertible always brings a little extra curiosity with it, and that is exactly why it belongs in a lineup like this. Mecum lists Lot W60 with a 2.7L flat-six and an automatic, a combination that suits the car’s easygoing personality perfectly.
The Corvair never fit neatly into the same box as most American cars of its era, and the Monza convertible only deepened that sense of individuality. It feels lighter in spirit, more unconventional in layout, and full of the kind of charm that makes people smile once they realize what they are looking at. At Mecum Indy, this one should appeal to buyers who enjoy open-top classics with a little extra personality and a little less sameness than the rest of the field.
2003 Chevrolet SSR Signature Series Convertible
The 2003 Chevrolet SSR Signature Series Convertible may be the biggest conversation starter in this group. Mecum lists Lot W111 as No. 8 of 25 Signature Series SSRs produced, with just 1,358 miles, previous ownership by Roger Penske, and a story that goes far beyond the truck’s already unusual retro-roadster formula.
Mecum says this example was part of Chevrolet’s special launch program, later received an Indianapolis 500 Pace Car conversion by Wheel to Wheel in Troy, Michigan, and wears PPG Ultra-Violet Blue with a Platinum Pearl Ice Indy 500 flame package. That makes it part retro truck, part promotional artifact, and part Indianapolis spectacle. At Indy, that combination of rarity, history, and event-specific personality should make it one of the easiest vehicles in the sale to remember.
1959 Chevrolet Corvette Convertible
A 1959 Chevrolet Corvette Convertible always knows how to command affection, and this one does it with a distinctly custom flavor. Mecum lists Lot W107 as a body-off-the-frame build by Mel Bryson and Sons of Vida, Oregon, with 6,000 miles since completion, a 350/350 HP ZZ4 V-8, dual Edelbrock 4-barrel carburetors, and a 4-speed manual.
It still carries the graceful late-1950s Corvette silhouette that made the C1 such a lasting American icon, but the upgraded mechanical package gives it a stronger and more purposeful voice. At Mecum Indy, it should appeal to buyers who love classic Corvette style but also appreciate a car that has been reimagined with confidence rather than preserved so carefully that it forgets how to feel alive.
2003 Bentley Azure Mulliner Convertible
The 2003 Bentley Azure Mulliner Convertible brings a completely different kind of open-air appeal to Wednesday’s lineup. Mecum lists Lot W109 with a twin-turbocharged 6.75L V-8, automatic transmission, tan leather interior, and an original MSRP of $410,000. Before the engine even starts, those details tell you this is a car built around scale, craftsmanship, and effortless presence.
The Azure has always felt less like a roadster and more like a grand occasion on wheels, something designed to turn distance into pleasure without ever asking its occupants to rush. In Mulliner form, that sense of occasion only gets stronger. At Indy, it should attract buyers who want their performance delivered through comfort, prestige, and the kind of confidence that never needs to shout.
2002 Pontiac Trans Am Convertible
The 2002 Pontiac Trans Am Convertible closes the group with exactly the right dose of late-era muscle attitude. Mecum lists Lot W69 as one of 32 Sunset Orange convertibles equipped with a manual transmission, and it pairs that rarity with the WS6 package, a 5.7L/325 HP V-8, a 6-speed manual, black leather interior, and 39,000 miles showing.
The color alone gives it instant visual punch, and the WS6 specification adds the sharper, more aggressive flavor enthusiasts want from a fourth-generation Trans Am. At Mecum Indy, this car should resonate with buyers who remember exactly how much presence these Pontiacs carried when new and still feel that same spark when one appears with the right options, the right color, and the right open-top drama.
