Photos : This One-off Mercedes E-Class-based 1989 Boschert B300 Gullwing Set To Fetch $315,000

RM Sotheby’s expects 1989 Boschert B300 Gullwing to fetch between $265,000 and $315,000 on November 25.

Based on a 1989 Mercedes-Benz 300CE, it features a front end and front seats taken from an R129 SL Class.

The one-off Boschert B300 made its grand debut at the 1989 Frankfurt International Motor Show.

But this example from a planned 300 units was the only one to sport the head-turning trademark gullwing doors.

Its 283-hp 3.0-liter engine allows it to accelerate to 60 mph in under 6 seconds. It is capable of reaching a top speed of around 165 mph.

Collector car auction company, RM Sotheby’s, is auctioning off a one-of-a-kind 1989 Boschert B300 Gullwing on November 25th 2023 in Munich, where it is expected to fetch between $265,000 and $315,000.

The extraordinary 1989 Boschert B300 was created by German engineer Hartmut Boschert, whose work was also inspired by tuner Styling-Garage’s 2-door C126-based 500SGS Gullwing from the early 1980s.

Based on a 1989 Mercedes-Benz W124-generation 300CE, the heavily modified Coupe features a front end and front seats taken from an R129 SL Class and special Boschert badgings to distinguish it from a stock Mercedes.

But the highlight of the Boschert B300 design was its gullwing doors first seen in the Mercedes-Benz 300 SL introduced in 1954 — a Grand tourer which was voted the “sports car of the century” in 1999.

The Boschert B300 first made its grand debut at the 1989 Frankfurt International Motor Show, but this example from a planned 300 units was the only one to sport the head-turning trademark gullwing doors.

Powering it is a twin turbocharged Mercedes-Benz M103 3.0-liter engine, producing 283 horsepower and 220 lb-ft of torque, which allows it to accelerate from 0 to 60 mph in under 6 seconds. It is capable of reaching a top speed of around 165 mph.
