Welcome to the Nostalgic Motor Cars Technical Library. For nearly 50 years, my only full-time job has been the service and preservation of 1963-1985 Avantis. These articles are compiled from my personal experience and original Studebaker factory blueprints to help you maintain the safety, value, and authenticity of your car.
