Open-Top Electric Excellence
The Gostwyck Spyder represents the perfect fusion of classic British roadster styling with cutting-edge electric propulsion. Born from a passion project during the 2020 lockdown, this unique vehicle combines the timeless elegance of 1960s sports cars with modern electric performance and safety.
Built on a BMW Z3 chassis and clothed in a meticulously crafted fibreglass body, the Spyder offers an authentic vintage driving experience without the emissions. Every component has been carefully selected and integrated to create a truly unique electric roadster that turns heads wherever it goes.
This is more than just a conversion – it's a complete reimagining of what an electric sports car can be.

The Build Story
The Spyder project began in 2020 as a family lockdown project and evolved into a comprehensive 4-year build. Starting with an MOT-failed BMW Z3 purchased for £800, the car required extensive bodywork before the electric conversion could begin.
The transformation involved removing the entire ICE drivetrain and replacing it with a carefully orchestrated collection of electric components from various manufacturers. The result is a truly unique vehicle that combines the best of classic automotive design with modern electric propulsion.
