Collections come in various shapes, forms and sizes, with some even being more expensive than others. That's nothing in the auto industry where you have people with the financial resources to collect some of the expensive vehicles in the world.

But when it comes to Dodge Vipers->ke1404, this couple from Texas trumps all of them -- by a lot.

Apparently, they're every bit the passionate Viper fans they make themselves out to be. In the past seven years, they've taken a significant chunk of their wealth and used them to buy Vipers. Not just one, two, or even 10 models.

65 models, in fact.

D'Ann and Wayne Rauh are the proud owners of 65 Dodge->ke28 and SRT Vipers, a collection that could arguably be the largest Viper collection in the world. Now, there might some Middle Eastern->ke3761 man that has an equally huge -- maybe even larger -- collection out there, but for what it's worth, the Rauh's collection of Vipers is pretty incredible.

What makes their collection all the more impressive is that it only started its Viper collection in 2006 when they brought their first model. Soon thereafter, one model turned into two and two turned into four. Seven years later, their garage has just about every Viper you can think of, including the 2010 SRT10 ACR-X which isn't even street legal.

Now that's how you turn a fascination into downright obsession.

2013 SRT Viper

One of the fanciest American sports cars->ke506 in modern time, the SRT Viper->ke4220 is built to look good while also boasting the power that can give you goosebumps. That typically what happens when you have an 8.4-liter V-10 engine that hits 640 horsepower and 600 pound-feet of torque, allowing the sports car to hit 60 mph in the low three-second range while also boasting of a top speed of 206 mph.
