Even among the ranks of the world's most unattainable vehicles – Ferraris, Lamborghinis, Bentleys and such – there are some rides that stand out from the crowd.

Robb Report, a standard in luxury lifestyle publications, released its annual "Best of the Best" list, which features the cars that it sees as being the most exceptional new products on the market.

Here's a taste of the list and, before you ask, no, you can't afford any of these (and neither can we). But they're still pretty awesome to look at. Head on through and dream about owning one of these dream cars. 

Sedan: BMW M6 Gran Coupe

Sticker Price: $115,300
Invoice Price: $106,075
Fuel Economy: 14 mpg City, 20 mpg Highway

Although it has the word "coupe" in the name, the M6 Gran Coupe is actually a sedan. A very, very fast sedan. Powered by a beastly twin-turbo 4.4-liter V8 engine, the M6 produces 560 horsepower and can sprint from 0-60 mph in just 4.5 seconds. The Gran Coupe isn't the most attractive vehicle in BMW's line right now, but its power coupled with those wonderful German handling dynamics make it a lustful machine in a different way.

Coupe/GT: Rolls-Royce Wraith

Sticker Price: $284,900
Invoice Price: NA
Fuel Economy: 13 mpg City, 21 mpg Highway

Here's a small taste of what you get when you can fork over the $284,900 for the Rolls-Royce Wraith: a 624-horsepower V12 engine, a Starlight perforated leather headliner with 1,340 hand-sewn fiber-optic lights, wool floormats and more leather, chrome and woodgrain than you can shake a stick at. This vehicle is the acme of luxury, though you'll have to provide your own Grey Poupon.

Convertible: Porsche 918 Spyder

Sticker Price: $845,000 - $929,000
Invoice Price: NA
Fuel Economy: NA

If you thought the $300,000 Rolls-Royce on the previous slide was pricey, here's something that will make your jaw drop: You can buy about three of them for the price of one Porsche 918 Spyder, the German automaker's incredible new hybrid supercar.

"Wait, a hybrid?!" you say. That's right. Green technology isn't just for boring commuter cars anymore. The 918 employs a 4.6-liter V8 engine along with two electric motors to produce a bonkers 608 horsepower and 398 lb-ft of torque. This machine is a technical marvel – one you'll be hearing about for years to come.

Sports Car: Ferrari 458 Speciale

Sticker Price: $288,000

The gorgeous Ferrari 458 Speciale is a car enthusiast's dream. Powered by a 597-horsepower 4.5-liter V8, this supercar can sprint from 0-60 in an estimated 2.9 seconds. That's faster than the time it takes to pour a small cup of coffee. The 458 Speciale's handling is impeccable, too. As Autoblog put it: "Driving the 458 Speciale through a familiar canyon at speed is more wondrous than your prom, wedding night and birth of your first child combined." Sign us up.
 

SUV/Wagon: Mercedes-Benz E63 AMG Wagon

Sticker Price: $102,370
Invoice Price: $95,204
Fuel Economy: 15 mpg City, 21 mpg Highway

Contrary to popular opinion, wagons do not have to be boring family haulers and errand runners. The Mercedes-Benz E63 AMG Wagon is a perfect example of this. With its 577-horsepower twin-turbo 5.5-liter V8 engine, bellowing exhaust note and excellent handling, this is one of the most thrilling vehicles one can drive. Considering it comes with much more space than a sedan, why wouldn't you opt for the vehicle with the hatchback?
