1984 Maserati Biturbo Spyder

In 1984, Maserati chopped off the roof of the Biturbo to create this stylish four-seater convertible. Like the tin-topped versions, it wasn’t without issues, and as well as suffering from niggling build and quality issues, premature corrosion was a very real problem. Image and prices dropped massively in a short amount of time, from which the Biturbo is only now beginning to emerge. Despite low classic values, there’s a real sense of the exotic when it comes to keeping a Biturbo on the road, while restoration costs can be horrifying – especially when it comes to the engine.
