Cadillac’s Ciel Concept somehow wheels all the way back around from ridiculous and excessive back into a would-be place on our driveway. Pairing a lithium-ion battery with a twin-turbocharged 3.6l V6, there’s little better than an overzealous convertible for that dream west coast Cali drive. With the interior boasting wood and luxurious leather, 22-inch brushed nickel plated rims, carbon ceramic brake rotors, a power-assisted transmission shifter and heating and cooling in all the seats, get your chequebooks out for when the Ciel makes production.
