Winning the lottery and building the coolest car collection possible is a dream many a car enthusiast has enjoyed. Taking that dream a step further, we thought about the practical aspect of hunting down our dream rides. To streamline what could be an arduous process and to avoid the hassle of visiting various dealerships we thought it would be best to look for a single dealership that could help us fill our dream collection.

Our friends over at Marshall Goldman Motor Sales in Cleveland, Ohio may be the perfect spot. This massive facility houses over 200 pre-owned cars from a range of brands including Audi, BMW, Mercedes, Porsche, Rolls-Royce, and much more.

We asked the dealership how they have so many cars in stock. We assumed that most cars were consigned, but learned that consignments are actually illegal in the state of Ohio. Which is why Marshall Goldman owns every car in stock and has all the titles present. Based on "owned inventory," that could make them the biggest luxury dealer in the world.

Their inventory contains cars of all price categories but we wanted to pick out ten of our favorites that we'd add to our dream collection. We made our picks without paying attention to budgets - because if you're gonna dream, you might as well dream big.

2015 Aston Martin V8 Vantage GT

Marshall Goldman has many Aston Martin cars in its inventory but we chose this 2015 V8 Vantage GT. Why? This one has the rare six-speed manual transmission option. Power comes from a 4.7-liter V8 producing 420 horsepower but the real joy comes from rowing your own gears. This Obsidian black model only has 4,200 and originally retailed for $119,772. It is now being offered for $79,900.

2015 Audi R8 Spyder

Although this 2015 Audi R8 Spyder only has the 4.2-liter 420 hp V8 rather than the 520 hp V10, we chose it because it comes with the rare gated six-speed manual transmission. This one only has 10,200 miles on the odometer and is being sold for $95,900.

2001 BMW Z8

The BMW Z8 was one of the most interesting cars BMW ever built. Prices tanked because people didn't appreciate the Z8 when it was new but now prices have surged past what they were when it was new. Power comes from a 4.9-liter S62 V8, which is shared with the E39 M5. It produces 400 hp going out to the rear wheels though a six-speed manual transmission. This 2001 model only has 5,600 miles on it and is offered at $198,900.

2001 Ferrari 550 Barchetta

What would a car collection be without a Ferrari, right? That's why we went for one of the rarest cars in Marshall Goldman's inventory, a Ferrari 550 Barchetta. Ferrari only built 448 of these back in 2000 as a send-off for the 550 and this one is number 419. The Barchetta's 5.4-liter V12 sends 478 hp out to the rear through a six-speed manual transmission. This particular example has just 674 miles on it and even includes the complete books, tool kit, car cover, and full factory luggage set. No wonder why it costs $729,900.

2006 Ford GT

Ford GT prices have been on the rise, especially the limited run Heritage Edition, of which only 345 were built. This pristine example only has 269 miles on it, which is why it costs $468,900. The car includes the original window sticker and purchase documents as well as a 5.4-liter supercharged V8 producing 550 hp.

2012 Lexus LFA

This Steel Grey Lexus LFA is number 321 of only 500 built. Only 678 miles have been put on the car, which is why it commands a $486,900 asking price. The Yamaha-built 4.8-liter V10 engine is one of the best sounding engines ever produced and puts out 553 hp.

2014 Mercedes-Benz SLS AMG Black Series

Even in the insane world of AMG, the Black Series models sit above the rest. The SLS AMG Black Series was one of the best because it raised output from the 6.2-liter V8 to 622 hp while decreasing torque because the base SLS already had a reputation as a tire-shredder. This 2014 example is one of only 30 yellow models sold in the US and only has 4,000 miles on it. It is now being offered for $398,900.

2011 Morgan Aero SuperSports

All of the cars on this list are unique but we stopped dead in our tracks when we saw this 2011 Morgan Aero SuperSports painted in a unique shade of Medium Ivory. We've never seen another Aero SuperSports for sale in the US and Morgan only built 200 for the whole world. It is powered by a 4.8-liter BMW-sourced V8, producing 368 hp. With just 499 miles on it, this one is offered at $328,900.

2005 Porsche Carrera GT

It hard for us to pick our favorite car of all time but the Porsche Carrera GT is certainly up there. The Carrera GT is one of the last analog hypercars, characterized by a 603-hp 5.7-liter V10 sending power out through a six-speed manual. This GT Silver model has done just 1,079 miles and is being offered for $796,900.

2009 Rolls-Royce Phantom Drophead

Most of our choices are sports cars and supercars but we wanted to choose at least one car we could comfortably drive around every day. Instead of choosing a four-door Phantom, we chose the much rarer Drophead Coupe. It is essentially a convertible version of the sedan with the same 6.75-liter twin-turbo V12 producing 453 hp. In 2015, this car was sold for $464,800 but is now being offered for $167,900 with just 9,300 miles on it.
