I recently bought a 1928 4 dr phaeton. This car was owned by the same family since new. It has been parked in a barn since 1964 & not driven. My question is I bought this car to sell. Is it better to leave it the way it is (surface rust but nothing serious) or restore it. I am having the engine & trans rebuilt, but nothing else. The radiator has been boiled out and is good with 5 lbs of pressure.
