We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about. -- Petrolicious brings us an awesome VWvortex forum thread packed with prototype photos, design proposals and concept sketches of everything from the Iso Grifo to the 1994 Mustang.

New Audi A3 Cabriolet starts at £25,790 – first deliveries April 2014

New Audi A3 Cabriolet starts at £25,790 – first deliveries April 2014 The new Audi A3 Cabriolet – the fourth member of Audi’s A3 range – was revealed in September at the Frankfurt Motor Show and now, with first deliveries expected by spring 2014 in the UK, Audi has revealed the new drop-top A3 will cost from £25,790. That will buy you in to the entry-level SE trim which comes with a fully automatic roof in black, 16″ alloys, AirCon, MMI radio, iPod connection, DAB, Bluetooth and prep for an SD card Nav. The Sport and S Line sped A3s sit 15mm lower than the SE and get an acoustic folding roof in a choice of black, grey and brown and you can, if you wish, opt for the softer SE suspension or, if your season ticket for the chiropractor is up to date, spec the S Line with sports suspension.
