The Spada Codatronca Monza will be revealed officially later this month at the Top Marques show in Monaco, but pictures of the finished car have leaked out.

Using a Corvette Z06 7.0-litre V8 engine, the Monza is an open-top roadster version of Spada's low-volume production coupé. Designed by company boss Ercole Spada, the Monza comes with twin superchargers to take power to 700bhp.

The leaked images show the Monza will come with a cut-down Perspex screen and twin headrest humps to give the Monza a much more aggressive look than the coupé model.

Aimed at wealthy trackday enthusiasts, the Monza is expected to cost from around £250,000. It will have a 0-62mph of about three seconds and top speed is reckoned to be 210mph, which will be more than fast enough in a car without a roof.
