Throttlestop is more than just a facility that sells luxury automobiles. Founded by lifelong friends Jim Balestrieri and Tom Kostrivas, Throttlestop is the cumulation of decades of passion for cars, motorcycles, and racing. Both founders have an extensive history working in the automobile industry. As kids, Jim and Tom competed against each other racing “anything with wheels.” These beginnings led Jim to become a regular racing circuit competitor at Road America, a passion he has now passed down to his son. Meanwhile, Tom was hard at work managing his own luxury automobile leasing company in Milwaukee. Together, and with the addition of General Manager Nic Piekarski, the team came together to combine their passions into building Throttlestop in Elkhart Lake, WI.


Throttlestop was built to share our passion for automobiles with others by consigning and sourcing luxury cars, showcasing our museum of limited-edition motorcycles, and providing exemplary detailing and storage services to owners seeking to protect their prized vehicles.
