hi everyone
sorry to be basic but dont know a lot about cars let alone this bristol i've just become the proud owner of !!!
could someone give me a rough idea of value of a c reg bristol just become the owner due to repayment of a debt and have no idea what its worth.its been stood for several years in a dry farm building and is complete the car has been covered up and bodywork looks very straight and relatively rust free the interior is also complete although the driver seat has come apart on the stitching .
its brown in colour
cheers
