Hardtop convertibles – called coupé-cabrios across the pond – are commonplace enough these days that seeing one out on the road, as nifty as they are, isn't such a novelty anymore. Long before the first-generation Mercedes-Benz SLK, before the Mitsubishi 3000GT VR-4 Spyder, but significantly after the Ford Skyline Fairlane, a German garage by the name of Treser chopped the roof off the rally-bred Audi Quattro coupe and fitted a fully automatic retractable hard-top. Only 39 were made, of which only one was reportedly made in right-hand drive (apparently for a British customer), and that vehicle is on sale now on eBay.

In addition to the trick roof, which disappears in 20 seconds below a hard boot-lid at the touch of a button on the b-pillar, Treser also tinkered with the engine, coaxing 250 horsepower out of the turbocharged inline-five.

The seller claims the car cost £41,144.25 new, but as of when this here article was written, the bidding was at £7,645.01. For all the juicy details, check out the auction by clicking here.
