SALES DEPARTMENT

JERRY KOOP JR.
General Manager

I have spent the majority of my life in the car business!  Started in the detail department while in Junior High, then on to selling cars in 1983.  From there I worked my way up to the business office and spent several years doing that.  My next stop was as a sales manager and now I am the acting general manager.  I've been married to my wife since 1983, the same year I started in sales!   We have 3 wonderful kids and 5 grand kids (so far!)  On our spare time we love to travel, camp, and play golf for relaxation.  I look forward to assisting you on your next visit!

LINCOLN VANDRIE
Sales Associate

Born and raised in the area, I have been in automotive sales since 2017.  In 2020 I was a GMC 'Mark or Excellence' award winner for superior sales volume and customer satisfaction.  I am very family oriented and customer service driven, both demonstrated by a high client family and friend referral rate.  I enjoy hunting, boating, cooking and snowmobiling with Joy, my wife of 25 plus years, two boys (Jacob-23, Johnathon-18), friends and a large extended family.  My friendly, low key and trustworthy personality makes the sales process comfortable, and like my current customers you'll be back time and time again for a family style vehicle buying experience!  I look forward to assisting you on your next vehicle transaction!
