Riverhead Buick/GMC

In 20 years of offering a car as a hole-in-one prize at golf outings at least 10 times a year, Riverhead GMC never had a golfer sink the ball into the cup with one swing — until this summer.

Riverhead Motors is a family-run company, owned by partners Sternlicht and Lucki. Across all of its dealerships, the company employs more than 100 people, including technicians, sales and administrative staff.
