Which is why this incredibly rare 1989 Boschert B300 "Gullwing" is making me swoon, because it's essentially a mashup of my two favorite Sacco designs *and* was given the coolest style of doors possible. The best part of it all is that it's heading to an [RM Sotheby's]() auction on November 25. The car started out life as a W124-generation Mercedes 300CE, one of the very best looking coupes to ever wear the Silver Arrow. Then, German engineer Hartmut Boschert chopped it up. He cut into the car's roof structure and chassis, shortening its wheelbase by almost 10 inches, and fit it with gullwing doors. Boschert then grafted on the face of an R129-gen Mercedes SL-Class and gave it his own emblem, which happens to resemble an upside down Mercedes logo. The result is a car that looks almost like a German [Autozam AZ-1](). Inside, the B300 Gullwing gets a R129 front seats, with a reupholstered purple interior. ![]() ![]() ![]() ![]() ![]() Boschert kept the original car's 3.2-liter inline-six engine but boosted it with twin turbochargers, bumping its output to 283 horsepower. All that power goes through a five-speed manual transmission to the rear wheels. Originally, 300 of these beauties were supposed to be built but Boschert was only able to craft a handful, which makes this car incredibly rare. In 2023, this B300 received a massive overhaul, to keep it looking 1980s-fresh. It had a $17,159 mechanical service, $8,236 worth of paintwork, and a $5,048 leather repair. ![]() ![]() ![]() ![]() According to RM Sotheby's, the Boschert B300 Gullwing could sell for as much as $320,000. There are countless cool cars that you can buy for that kind of money, but I'd argue that a gullwing 1980s Mercedes with a straight-six and a five-speed manual is cooler than all of them. Now I just need to resist calling my realtor to find out how much I can get for my house. I hear it's a seller's market. *Got tips?

His love of cars began when he was just a kid playing Gran Turismo 3, grinding out enough race wins with a Mazda Miata to save up for an in-game RUF 911. That passion for small, lightweight sports cars drove his desire to learn more about the industry, get his hands on as many cars as he could, and bring those experiences to life on the page. He cut his teeth writing about BMWs, Volkswagens, and Audis, mostly, and has owned far too many of each. He’s on his fourth 3 Series sedan, but all of his old, cheap German cars have forced him to learn more about car maintenance than his mechanical capability can handle. Too many late nights have been spent scrambling to get a car running by morning so he could get to work. For some reason, he never seems to learn that old Bimmers probably aren’t the best daily drivers. But he loves more than just old German cars. He’ll gladly drive and discuss anything with four (or even three) wheels. Cars aren’t his only passions, though. Nico is also a big nerd and loves movies, video games, comic books, and cares far too much about the New York Giants. So don’t be surprised if you see football references or dumb, obscure movie quotes in any of his car reviews. ### Author social links [Instagram]() [LinkedIn]()
