When it comes to limousines, luxury is key. However, with just about rental company converting vehicles like the Cadillac Escalade and Hummer H2, the competition needs to a be a bit more adventurous. Continue reading to see five of the coolest limousines — image above via.

1. Boeing 727

This Boeing 727 limousine may not fly, but it could quite possibly be the coolest ever. According to the builder, “it’s 53 feet long and can carry a whopping 50 people in total luxury.” Unfortunately, this vehicle may not be street legal.

2. GP Limo

At first glance, the GP Limo looks like a stretched IndyCar vehicle, but it’s actually a limousine capable of hitting speeds in excess of 200mph. Michael Pettipas managed to break the 300mph barrier in a one-off model during 2005 at the Utah Salt Flats.

3. Tank Limo

Yes, the Tank Limo isn’t some joke and can actually be rented for special occasions. It may not be very luxurious outside, but on the inside, you’ll find plenty of seating, a few DVD players with displays, and a mini fridge to boot.

4. Corvette C6

Are you a fan of gullwing doors, Corvettes, and limousines? Then this custom-made Corvette C6-based vehicle should be added to your shortlist. Unlike the other entries here, this limousine features an electric fireplace and even a disco-themed interior, complete with dance floor.

5. Ferrari 360 Modena

At 23-feet long, the Ferrari 360 Modena limousine can go from 0-60mph in less than 6-seconds — though not as quick as the GP Limo above, this one is street legal. Inside, the vehicle has been fitted with a six speaker surround sound system, DVD player, 10-inch LCD display, and integrated cameras for road viewing.
