Throttlestop

Throttlestop is a consignment-focused collector car and motorcycle dealer at 20 Victory Lane in Elkhart Lake, Wisconsin, about two miles from the Road America race circuit. It was founded by two lifelong friends, Jim Balestrieri and Tom Kostrivas, and it combines a car showroom, a large rotating motorcycle collection, storage and detailing services. Directory and tourism descriptions say the facility opened in the summer of 2017.

Who is behind it

According to the company's story page, the founders raced "anything with wheels" as kids. Jim went on to become a regular competitor at Road America, while Tom ran his own luxury car leasing company in Milwaukee. They built Throttlestop to combine their interest in cars, motorcycles and racing. The site describes the business as consigning, selling and sourcing cars, showing limited-edition motorcycles and offering detailing and storage.

Consignment and how selling works

Most of what Throttlestop sells is consigned. Its consignment page says the process starts with an application, then a multi-point inspection if the company is interested in the car, followed by a professional photo shoot and a listing on its site and on other classic car marketplaces. The company says rates start as low as 7% and claims a 90% sell-through rate; both are its own statements, so ask for the fee schedule in writing.

What it sells

The stock is a mix of classic, sports, muscle and luxury cars at the upper end of the market, and its website promotes the company as a classic Jaguar specialist. In October 2026 the featured inventory included a 1963 Chevrolet Corvair 95 Rampside pickup at $38,900. Earlier listings on a major classic car site spanned about $24,900 to $399,900 and included Shelby-related and race-bred cars. The company says its showroom holds about 75 cars at a time.

The collection and other services

• Motorcycle collection: the company says it displays more than 200 historic motorcycles, plus a collection of engines, in a museum-style space that visitors can tour.
• Storage: climate-controlled, indoor concierge storage.
• Detailing and protection: offered alongside sales.
• Car finder and financing: the site lists a car finder service for sourcing specific vehicles and a financing page.
• Venue rental and events: the site has pages for both, including a 2026 events calendar.

Reputation

Review aggregators show high scores. Birdeye lists a 4.9 rating from 214 reviews, and a search summary of Kelley Blue Book reported 5.0 from 153, though we did not open that page. Yelp has too few reviews to use. We could not find a Better Business Bureau profile. Scores like these reflect past customers, so as with any dealer, ask for service records and title details and consider an independent inspection on a high-value car.
