Project Car Hell: BMW-powered Opel Olympia vs. Aston-equipped Singer Nine

Editor's note: When you can't fit your newly acquired basket-case Jeep FC150 in the garage because you have an Autocar Sussita and a 1928 Studebaker President chassis buried beneath crates of Subaru 360 parts, you're in Project Car Hell.

General Motors pulled perhaps a surprise at the Detroit Auto Show Sunday morning, unveiling an eye-catching two-door Cadillac concept powered by a "future evolution" of the Chevrolet Volt's electric powertrain. Called the Converj, the Cadillac will have a range of 40 miles on electricity, with a potential total range of 700 miles after a generator kicks in.

CarFest North & CarFest South 2013: Dates & Venues

Chris Evans’ CarFest North and CarFest South are back on again in 2013 with much motoring madness and a great day out for all the family.

Just like last year, CarFest South will take place at Laverstoke Park Farm - Jody Scheckter’s home – with an even bigger hillclimb and three evenings of live music, masses of food choices and, of course, cars galore.
