You may just want to rent a luxury car for the day to tool around in. If so, "regular" rental car agencies like Enterprise or Hertz offer high-end rentals. They can be rented by the day or for several days and will cost from $1,500 to $3,000 for the day. You can also rent an exotic car from a company that specializes in luxury car rental, usually smaller, local, private companies (i.e., they're not likely to have a desk at the airport).
But you probably want to take it up a notch. Oxotic offers a unique rally-style drive experience by taking clients on tours through the foothills of the Rocky Mountains in their fleet of cars that includes a McLaren, Lamborghini, Aston Martin, Mercedes and Ferrari. A road rally drive is a scenic drive over a specific distance, sometimes with participating cars in a convoy together. Oxotic does 15, 25, 35, 60 and 105-mile tours, each highlighting different state parks known for their scenery and winding roads. On longer trips, people have the option to drive more than one car. Prices range from $95 to $1,000.
"People come in from everywhere in the world to drive with us," says Eric Sandoval, owner of Oxotic. "We are the only rally-style drive in Colorado and people love that they get to experience each car, then have video and photos of themselves driving in the mountains." (You can look for other scenic tours at Xtreme Xperience or Ultimate Driving Tours.)
Another option is traveling companies that tour through various cities across the country, rent a stadium or a racetrack for a weekend, bring their fleet of cars and let drivers take a seat behind the wheel. Depending on the make and model, doing three laps could set you back around $350 to $400.
Luxury car manufacturers often have their own driving experiences. For instance, the Mercedes-Benz AMG Academy offers one-day to three-day experiences, ranging from methods to improve driving skills to rally-style events to classic car tours, all using Mercedes-Benz cars, of course. The Porsche Driving Experience has centers in Atlanta and Los Angeles that offer track racing and driving coaching, using the Porsche fleet.
