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.

There’s a reason the new Ferrari 458 Spider has got a massive grin on its face. Slotting nicely into the legendary car manufacturer’s mid-engine line-up, the 458 Spider features a retractable hard top, 4.5l V8 under the hood, packing 562bhp, Ferrari’s dual-clutch F1 paddle-shift transmission and some humongous 20-inch rims. Price is TBA, though it isn’t going to be cheap when it hits dealers early 2012. If you’re tempted, we’d advise getting in line.

Up for grabs on August 20th at RM Auctions, this 750 Monza Spider is one of only 35 ever built, and with 260 bhp under the hood and a DOHC four-cylinder engine and five-speed manual transmission, it’s no surprise it’s expected to fetch between $2.5m-$3.25m. Even the car has a cheeky grin on it, though picture your own when cruising down the coast. Oh, and that mini cover comes off to reveal space for one very lucky passenger.

To be auctioned on August 20th, this 1965 Mercer-Cobra Roadster would make quite the addition to any collector’s garage, or one hell of an Sunday motor, as long as you don’t mind a little maintenance. The V8, four-speed roadster by the Lyon Family Collection since 1989, currently in tip top condition and boasting a glorious 108-inch wheelbase, though you’ll have to shell out an estimated $800,000-$1,200,000 to make it your own. Worth it.

As the G-Class enters its final dawn, if the Mercedes-Benz‘s BA3 Final Edition is the classic off-roader’s last hurrah, it sure goes out with a bang. In a sleek, dark monotone, it’ll gobble up the wilderness for breakfast, packing a 5.5-liter V8 388bhp engine in the G500 model, plus Benz’s 7G-TRONIC seven-speed automatic transmission.

There are few cars we like more than a Prosche 911. A vintage Ferrari would probably do it, or a Mk. IV Ford GT40, but good luck getting your hands on one of those that doesn’t also require the hiring of a 24-hours mechanic. So back to the 911 it is, or if you’re not a millionaire, the perfectly mid-spec Porsche Cayman S Black Edition. Adapted from its cousin, the Boxter S, Porsche’s Cayman S Black Edition packs a hefty 330 horses under the bonnet, as well as a six-speed manual or Porsche-Doppelkupplungsgetriebe (thankfully dubbed ‘PDK’) seven-speed double clutch transmission. Toting some suave 19-inch black wheels and monochrome black treatment on the exterior and interior, even at $67,500, with only 500 due for production, they’re bound to be snapped up very fast indeed.

I quite want this car, and to hire the stuntman as my diver; the BMW 1 Series M Coupé versus concrete walls.

The 1959 Ferrari 250 GT LWB California Spyder is easily one of the most beautiful cars ever in production, but even after the last run off the line, there were only 50 gracing the world. Odds are, you’re not one of the owners. With Prince Alvise Hercolani of Bologna’s model recently up for auction through RM Auctions, however, and a number more for sale in the last 6 months, they’re popping up ever more increasingly. With a removable hardtop and sumptuous Superamerica side vents, nevermind a surprising amount of power under the hood, full leather upholstery and the classic wooden steering wheel, it’s no surprise they normally pull around $3m.
