Lumpp Rent A Car has been a family owned and operated business for thirty years in the Shenango Valley. In 1981, George Lumpp opened and established Lumpp Rent a Car on Stambaugh Avenue in Sharon. In 1996, Paul Knott purchased the business from George Lumpp and decided to keep the name as it was already an established reputable rental business. We not only offer car and truck rental, but towing, pre-owned care sales, and service on all makes and models.
