In case you're not aware already in the early 1990s a Fench magazine called "Echappement" (French for exhaust) conducted a survey of readers asking what they would want a modern interpretation of the Alpine Renault A110 to be. The result of this was the Hommell Berlinette Echappement, built by a guy called Michel Hommell (who happens to be a mega Alpine enthusiast -aren't we all?).
The Hommell Berlinette is a mid engined space framed sports coupe which uses a tranverse mounted Pug engine and gearbox. The rear suspension is based upon the 405 front suspension. When production began they used a 405Mi16 engine and a Citroen motorsport six speed gearbox. After the 306GTi6 was released, they started using the GTi6 engine and gearbox. This car weighs less than 1000kg and is a pretty fantastic performer.
In November 1995, Cars and Car Conversions published an article on these cars, which I'm going to send to gibgib to put in the downloads section.
Do a search in Yahoo for "Hommell Berlinette" and you'll find a few websites with references to these cars.
