Hello.. I am considering a purchase of a 1923 Durant Doctor's Coupe. Great condition. Runs good. I just wanted to get a little information on the vehicle and what better place to ask. 1.) Does anyone know the history and the Doctor's Coupe and if it was originally manufactured by Durant or an after market update? 2.) what's the value of such vehicle? I have an asking price, just don't want to over pay. Thank you for your answers.
