Coachbuilt European classics have a funny way of hiding in plain sight. Everyone at the auction tent watches the big-ticket Ferraris, the Gullwings, and the movie-star Astons, but meanwhile, the sharp buyers study the weird badges, the small coachbuilder plates, and the cars that make experts lean closer without making influencers yell into a phone.The best buys in this lane do more than look pretty. They carry rare bodies, hand-finished details, odd engineering, and stories that do not fit on a coffee mug. These five cars cost real money, yes. Nobody finds one behind a barn unless that barn belongs to a retired count with suspiciously good taste. But each one gives collectors a deeper kind of charm — limited production, serious design houses, and enough mechanical personality to make a modern supercar feel like an appliance with wheels. Alfa Romeo 2600 SZ Zagato Price: $289,000 BaT The Alfa Romeo 2600 SZ Zagato looks like it arrived from a slightly different timeline, one where Alfa decided grand touring needed more attitude and fewer polite dinner jackets. Alfa’s standard 2600 already had charm, with a 2.6-liter twin-cam inline-six and a five-speed manual. Zagato then gave the car a lighter, lower, sharper body and turned the gentlemanly six-cylinder Alfa into something far more pointed. Only 105 examples of the 2600 SZ came from this small run, which gives the car real scarcity without the usual “please wire seven figures before lunch” attitude.BaTWhat insiders like here comes down to taste and timing. The 2600 SZ does not have the obvious beauty of a Bertone Alfa coupe – it has a blunt nose, a high rear, and a face that seems to ask, “So, what are we looking at?” But that is the appeal — the car sits near the end of Alfa's classic straight-six story, and carries Zagato DNA without TZ money. It also drives like an old-school Italian GT should — long-legged, mechanical, and a bit dramatic for no reason. In other words, it is an Alfa Romeo – of course it has feelings. Maserati Mistral 4.0 Spyder by Frua Price: $397,000 BaT The Maserati Mistral 4.0 Spyder by Frua has the quiet confidence of a car that does not need to flex. It pairs open-air elegance with Maserati's great inline-six tradition, the same broad family of engines that helped define the brand before V8s took over the front pages. The 4.0-liter Mistral Spyder uses a 4,014 cc straight-six, 265 hp, and only 37 examples produced in that specification.BaTThe Mistral also hits a sweet spot that many flashy classics miss. It has enough power to feel special, enough rarity to matter, and enough restraint to avoid looking like it belongs to a man named Count Something-or-Other. Frua gave it clean lines and a low, balanced shape, while the 4.0-liter engine gave it the relaxed punch a proper GT needs. The cabin feels more touring car than racer, which explains why insiders like it. Maserati Ghibli 4.7 Spyder by Ghia Price: $472,500 BaT Yes, another Maserati. The Ghibli 4.7 Spyder by Ghia may be the most obvious car here, but insiders still find the right examples worth looking for. Giorgetto Giugiaro shaped the Ghibli while working with Ghia, and the Spyder kept the coupe’s long hood, low stance, and clean muscle-car-meets-Modena mood. The 4.7-liter Spyder used a 4,719 cc V8 with 330 hp, and the company built only 83 examples of the standard Spyder before counting the later SS cars separately. That puts it in a far rarer group than many better-known open classics.BaTThe 4.7 Spyder has a second advantage – it lives in the shadow of the 4.9 SS. That sounds like bad news until collectors remember that shadows often lower prices. The standard 4.7 still has the look, the sound, the Ghia badge, and the full open-top experience. A 1970 Ghibli 4.7 Spyder by Ghia sold for $472,500 at RM Sotheby’s Monterey sale in 2025, which looks sane next to the top end of the Ghibli Spyder market. Lancia Flaminia Sport by Zagato Price: $555,000 The Lancia Flaminia Sport by Zagato rewards the kind of collector who cares about details. At a glance, it looks delicate and almost pretty. Then the nerdy stuff appears — Zagato gave early cars covered headlights and the famous double-bubble roof, a shape that helped headroom and stiffness while making the car look like it wore a racing helmet under its paint. The Flaminia Sport and Super Sport family stayed rare, and production figures vary depending on the source, with the dedicated register showing 599 Sport and Super Sport Zagato cars across the run.The best early cars have a special pull because they feel closer to coachbuilding as an art form than to normal production. A 1959 Flaminia Sport Zagato sold for $555,000 in 2023, which Classic.com lists as the highest recorded Flaminia sale. That price makes sense — the Flaminia Sport gives collectors Italian design, Lancia engineering, and Zagato rarity in one small, odd, elegant package. Pegaso Z-102 Series II Berlinetta by Touring Price: $800,000–$1.07 million The Pegaso Z-102 Series II Berlinetta by Touring feels like the car on this list that most people should know, yet somehow do not. Pegaso came from Spain, not Italy, Britain, or Germany, and the brand built trucks before it built one of the strangest and most advanced sports cars of the 1950s. The Z-102 used a sophisticated V8, a five-speed transaxle, and exotic coachwork from names such as Touring and Saoutchik. Classic.com lists total Z-102 production at only 83 examples, which makes even rare Italian GTs look common by comparison.The Touring-bodied Series II Berlinetta adds another layer. Gooding & Company described a 1955 example as one of only 10 Series II Z-102s, fitted with the larger 3.2-liter engine and lightweight aluminum Berlinetta coachwork by Touring of Milan. Its 2024 London estimate of £600,000 to £800,000 lands roughly in the $800,000 to $1.07 million zone, depending on exchange rates. This is not the easy choice, of course – parts support will not feel like ordering brake pads for a Mustang. But that is also why insiders care — the Pegaso is a deep-cut supercar before the word "supercar" had a PR department. It is rare, clever, expensive, and gloriously odd.Sources: RM Sotheby, Classic.com
