When some people dream of a second (or even third) home or property, they imagine views of a pristine lake or a peaceful golf course. Not Julie Hertzberg. When it was time for her to take the plunge, she wanted thundering V-8 engines and the smell of hot rubber on pavement.

Ms. Hertzberg, 46, a managing director in the Detroit office of the financial consulting firm Alvarez & Marsal, and her husband Robert Hertzberg, 65, a partner with the law firm Pepper Hamilton, bought a car condo. The 1,200-square-foot unit started out as an empty box, and the couple turned it into a two-floor space. On the bottom floor is a garage with a polished concrete floor. The couple’s 2016 Chevrolet Corvette Z06 (bought new for about $105,000) and 2017 Ford Mustang Shelby GT350R (about $65,000) are considered two of the most high-performance cars ever built at their price-points, while their 2010 Ferrari 458 (about $235,000 in 2010) is no slouch. When time permits, the couple can be found throttling these vehicles on the high-performance test track that sits right outside their condo. Otherwise, the cars make for gleaming sculpture pieces.

A Place to Race in Michigan

For the upstairs,” Ms. Hertzberg says, “we wanted a cigar-bar feel but also a functional living space.” There is a king-size Murphy bed for overnighters, a bar, kitchen, an entertaining space, plus a glassed-in bar space that looks out over the speedway, for spectating the action.

The couple’s car condo is in a development called M1 Concourse, built on 87 acres in Pontiac, Mich. The development has everything needed to draw in a highly specific clientele—car nuts. The winding track measures 1.5-miles long. There is a private motor sports club, and 173 car condos built and sold thus far. “There’s a special vibe to the whole place,” says Ms. Hertzberg. “You wouldn’t find it anywhere else.”

M1 Concourse is one of a growing number of developments nationwide aiming to draw car lovers into a wholly different kind of real-estate market. If there is wealth in a city or town, there are likely to be car collectors, and increasingly, car condo campuses. There’s Iron Gate Motor Condos in Naperville, Ill., outside Chicago, and Trove, outside Vancouver. There’s CollectionSuites outside Miami, and Monterey Motorsport Park in Monterey, Calif.

M1 Concourse is unusual for having its own performance test track. The first condos were completed in 2015. Purchasers bought an empty box and then built out their spaces as desired. The Hertzbergs purchased their space at a discount for $225,000 because they bought before construction was completed. Ms. Hertzberg says if she tried to sell that same 1,200-square-foot empty box today for $550,000, there would be a bidding war. They put $200,000 into the build-out, and the work isn’t done yet; they are planning to build an elevator lift, so they can carry a car from the downstairs floor upstairs, to make it a showpiece when they host parties.

Real-estate projects that focus on a motor sport concept face unusual challenges, including noise ordinances and permitting for gasoline pumps. M1 Concourse’s track is directly adjacent to a residential neighborhood in Pontiac. The original developer, 49-year-old Brad Oleshansky (who left the company earlier this year to create similar projects in other parts of the country) says the community embraced the project during development and construction in 2014 and 2015 because it was built atop a tract of land that was home to an abandoned General Motors factory.

Building M1 Concourse, Mr. Oleshansky says, required removal and environmental cleanup of “two million square feet of concrete, old steam tunnels, etc.,” materials that he says neighboring residents were happy to see gone. Meanwhile, the development created jobs and tax dollars for the community.

As for noise, Jordan Zlotoff, M1 Concourse’s current CEO, says that the cars on its track are typical production performance cars that are built with noise-damping features. “We don’t do wheel-to-wheel competitive races with actual race cars,” he says. There is no driving on the track after sunset, and there are restrictions on modified exhaust systems. (A phone call to the local police department in Pontiac confirmed there have been no recent complaints about noise.)

As for the price of the build-outs at M1 Concourse, Mr. Zlotoff estimates that owners spend anywhere from a couple of thousand dollars to roughly $1 million.

M1 has special street cred for another reason. It is located near the epicenter of American car history, just outside Detroit, the “Motor City.” “I’m a Detroiter,” says Laurie Cunnington, another M1 Concourse car condo owner. “Detroiters love their cars.”

Ms. Cunnington received her car condo as a gift from her husband in 2015. (They are both entrepreneurs and former co-owners of the Ward Williston Oil Co.) The cost: $275,000 for the 1,200-square-foot empty space, before the build-out. On the ground floor, Ms. Cunnington keeps a small collection of her rare Italian cars—a 1991 Lamborghini Diablo, a 2007 Ferrari F430, and a new vehicle that just arrived from Italy last month, Ferrari’s latest hardtop convertible, the Portofino. She is an unabashed fan of speed, and loves the fact that she has female neighbors in her development who, like her, enjoy using the track.

Upstairs, her car condo is a fully imagined entertaining space created by local designer Pamela McCarthy Designs, with lots of stainless steel accents and glass shelving. Ms. Cunnington wanted her space to be, in part, a paean to her home city, so the Detroit Wallpaper Co. custom-designed a panel for her with a pattern of Detroit street names and the names of Detroit-made automobiles.

“Everyone who has a place here knows everyone else,” she says of M1 Concourse, “and everyone is very friendly, because everyone shares this passion for cars.”
