Certificates of Authenticity

RENNtech Classics issues Certificates of Authenticity for vehicles built by RENNtech. Each car is reviewed in detail for original parts and modifications, and cross referenced to our build sheets and customer records. RENNtech CoA is the only official document available to certify that the vehicle adheres to the specifications it had at the time it left the RENNtech. Vehicles must be present at RENNtech Head Quarters in Stuart, FL for certification inspection. Please contact us to schedule an appointment for certification.
