Before anyone begins to even dream about owning any of these cars, we feel we have to give fair warning that purchasing any one of them will probably cost a few arms and legs. Of course, for anyone whose bank account has never felt the dryness that most of ours have, then listen up.

Forbes - yeah, we all know them - has released a Top 10 list of the World's Most Expensive Cars. Think forking over $100,000 on a car is already a financial burden? Well, think again. Not only are these cars fast and powerful, but they command a pretty steep price tag, which is only affordable to those people that have as much money as we have lottery tickets.

Something of note for this list is that there are two cars that have yet to be unveiled, let alone given a price tag. Their respective prices are then assumptions by Forbes and may change the list once the actual prices have been revealed.

Another thing that we noticed is the conspicuous absence of the Aston Martin One-77, which, at $1.77 million, is easily one of the most expensive cars in the world. Forbes normally covers a lot of holes on their list, but they clearly made one oversight there.

Check out Forbes' list after the jump.

Rolls-Royce Phantom Drophead Coupe: $447,000

The newest Rolls-Royce to come out of West Sussex also happens to be its most expensive. The new Phantom Drophead Coupe commands as much respect for its luxury and performance as it does for its price tag. The luxury ride is powered by a 6.75-liter naturally aspirated V12 engine that delivers an impressive 453 horsepower and 531 lb/ft of torque with the option of adding a teak deck made of 30 different pieces of fine-grain wood. As you can expect, Rolls-Royces don’t come cheap, and in the case of the new Phantom Drophead Coupe, that’s $447,000 you’re going to have to part with.

Lamborghini Murcielago LP670-4 SuperVeloce: $455,400

If the Drophead Coupe is all about riding in luxury, then the Lamborghini Murcielago LP670-4 SuperVeloce is all about riding at break-neck speeds. As one of the last special edition Murcielago models to come out of Sant’Agata, Lamborghini wasted little time in making this Murcielago a car nobody’s going to forget anytime soon. Inside this stunning piece of Italian machinery lies a 6.5-liter V12 engine that produces 670 horsepower and can clock a 0-60 mph time of just 3.2 seconds. Care for one? Do you have $455,400?

Ferrari SA Aperta: $520,000 (est.)

The first of four estimated price tags on this list belongs to a car that we first saw at the Paris Auto Show: the Ferrari SA Aperta. Built to celebrate the 80th anniversary of Pininfarina, the SA Aperta is based on the 599 GTO with an engine that’s nothing to laugh about, that is unless you classify a V12 engine that produces 670 horsepower as funny. Ferrari has yet to reveal an official price on the SA Aperta, although Forbes seems to think that it’s going to be somewhere around $520,000. This limited run Ferrari’s price tag is aided not just by its performance capabilities, but also because of its exclusivity, which, in case you didn’t know, limits the vehicle to 80 units.

LeBlanc Mirabeau: $728,000

Not a lot of people are familiar with this Swiss racer, but the street-legal LeBlanc Mirabeau just happens to be one of the most expensive cars on this list – and for good reason, too. It packs a supercharged V8 engine under its hood, producing a whopping 700 horsepower and 850 Nm of torque. And also, despite it’s race-aesthetics, the Mirabeau is absolutely street-legal, providing a car that’s going to grab attention like a basketful of magnets inside a hardware store. As for the price tag, well, let’s just say that unless you have about $728,000 at your disposal, you might want to think of a cheaper – and more practical – set of wheels to take around the block.

SSC Ultimate Aero: $750,000

Ultimate is as Ultimate gets. That’s how you describe the SSC Ultimate Aero, the one-time fastest car on the planet, thanks in large part to its monster V8 engine that produces 1,287 horsepower with a staggering top speed of 273 mph. Many have described the SSC Ultimate Aero as the Bugatti Veyron->ke1112’s kryptonite, and for good reason. Before Bugatti recently reclaimed the title of fastest production car on the planet, the Ultimate Aero held that lofty title, one in which they’re itching to get back. As for the price tag for one of these bad boys, it’s going to cost you $750,000. Speed has a price, so they say.

Ferrari F70: $870,000

Unless Forbes knows more than any of us care to imagine, number five on their list is a car that hasn’t even had its world unveiling yet. Yep, they’re talking about the successor to the Ferrari Enzo, a car that’s been christened as the “F70”. Not much is known about the “F70” other than its rumored to have either a V12 engine or a turbocharged V8 that produces somewhere in the neighborhood of 700 horsepower. Either way, Forbes is pricing the “F70” at $870,000, which is about $200,000 more than what its predecessor – the Enzo – was priced when it first hit the market about a decade ago.

Pagani C9: $1.3 million

Another car that’s yet to hit the market despite it’s apparent fondness for being photographed by ‘auto-razzis’ over and over again is the Pagani C9. Contrary to earlier reports, the new Pagani supercar will not come with an AMG-sourced V12 engine. Although AMG will still be tasked to build the new engine, it will be created specifically for the C9 with a rumored output of somewhere around 700 horsepower. The car will only be limited to 40 units and as such, Forbes is estimating that Pagani will be taking advantage of the law of supply and demand, putting in a price tag of $1.3 million for each model.

Maybach Landaulet: $1.405 million

As one of only two luxury cars to make it on the list, the Maybach Landaulet completely redefines the words ‘class’ and ‘luxury’. The chauffeur-driven limousine is based on the 62S and features a soft partial convertible top above the rear-sear passengers making for a pretty comfortable Sunday morning car. Talking about luxury, the Landaulet is one of the closest things you can find to a mobile hotel room. It comes with its own refrigerator, folding tables, and two champagne flutes hand-polished in 925 sterling silver. Further stressing its ‘luxurious’ image, the Landaulet is a car that can only be afforded by those who live and breath in luxury - people that can afford a car for $1.405 million.

Koenigsegg Agera: $1.5 million

Straight from the Scandinavian winds of Sweden is a supercar that breathes 910 horsepower and can accelerate ‘north to 60’ in just three seconds. As the latest masterpiece built by Swedish supercar maker Koenigsegg->ke43, the Agera is definitely in a class all its own. We’ve already touched on all those ponies under its hood, which is made entirely possible because of the 4.7-liter V8 engine underneath, but the Agera is also being touted for one advantage it has over its competitors: cabin and luggage space. Sure, it’s not the first thing you’re going to look at when you’re in the market for a supercar, but at an estimated $1.5 million – and we know that kind of money doesn’t just grow on trees - you’re going to take any advantage you can get.

Bugatti Veyron Super Sport: $2.6 million

The Holy Grail of all Bugatti Veyron models, the Super Sport isn’t just the most expensive car on the planet with a $2.6 million asking price, but it also happens to be the current record-holder of fastest production car on the planet having clocked a Guinness World Record speed of 268 mph. We’re pretty sure that that record is eventually going to be broken someday. But in the world of the present, the Veyron Super Sport stands head and shoulders above everybody else as the fastest, most powerful, and most expensive production car you’ll find today.
