If one day you find yourself in a Wal-Mart-size building in Florida and hear "cleanup on Aisle 3" over the loudspeaker, it's most likely transmission fluid or motor oil rather than a spilled carton of milk that needs to be mopped up.

This particular building in Punta Gorda once was a Wal-Mart — all 100,000 square feet of it. But should there be any spilled fluids, they would come from one of about 200 classic cars that are on display at Rick Treworgy's Muscle Car City.

The collection features an every-color-of-the rainbow assortment of mostly Chevy muscle cars, and dozens of them are Corvettes.

The 100,000-square-foot building that houses Rick Treworgy's Muscle Car City was once a Wal-Mart location in Punta Gorda, Florida.

"I grew up during the heyday of muscle cars, and between the ages of 16 and 24, that's all I played with. And they were mostly General Motors cars," Treworgy says. "Interestingly, my dad was a Ford man. But I bought and sold cars early on, and I just found the GM cars easier to sell and get parts for, so I became a GM guy."

The collection periodically changes as different cars are rotated into the display. Believe it or not, Treworgy has a large number of cars in his private collection that don't fit in the enormous display housed in the building now. So, some of them eventually get their turn on the floor as well.

It takes a camera's wide-angle lens to even begin to capture a partial view of the more than 200 classic muscle cars in Treworgy's car collection and display.

In addition to the mind-numbing display of some of the most desirable cars among car enthusiasts and collectors, the building also features a classic '50s-style dinner with burgers, fries and shakes — those menu items bring some visitors back just for the food. An adjoining gift shop offers all kinds of reproduction automobilia and car-related books and souvenirs.

But it's the cars most people come to see. And while the clientele represents a broad cross-section of age groups, a quick look around usually leads to the realization that most of those who visit are of a certain age, like Treworgy, who grew up with these cars.

"It was a special, fun time — the '50s and '60s. And you can't see these cars or listen to the music of that era without being mentally taken back to a unique, simpler and, in many ways, happier time to live," he muses.

The interiors of most of the Corvettes in the Muscle Car City collection appear to be factory fresh. Enthusiasts will note this big block roadster was ordered radio delete.

It's apparent to most that one doesn't acquire the ability to put together a collection like this by working at a Wal-Mart. In truth, Treworgy's financial success and ability to assemble these cars came from his savvy involvement in commercial real estate transactions through the years. And reportedly, one of his better deals early on, involved the sale of a pig farm that is now home to an airport.

Treworgy loves to interact with visitors and is quick with answers to myriad questions he gets asked about the cars every day.

"Another reason I enjoy talking to these folks is that many of them drive their own muscle cars to our place. And sometimes, they have cars I like, and it's not unusual for me to strike a deal with them and buy their car on the spot," he says. "One thing I learned a long time ago, you don't always buy just when you're looking for a specific car. If you see one you might want later, you'd better buy it then. Because it probably won't be available if you decide later."

The Corvettes are among his favorites in his massive collection, and he says it seems that most visitors gravitate to them initially. There are coupes and roadsters in the assemblage, and most display badging that indicates these cars were once kings of their respective roads.

And the only pigs to be found these days are in the diner — on the bacon cheeseburger.

The hood "stinger scoops" on this row of '67 Corvettes may be nonfunctioning, but the engines they conceal when closed are the real thing — mostly 427 big blocks.
