Considering selling my 1979 Rolls Royce Silver Shadow II or should say the wife wants me to sell it . All original has 83,000 miles. Some cracking in Leather , paint in perfect shape never wrecked or painted . Have all original manuals and a lot of service records on it . What’s the best place to find out a realistic value for it as I see them selling at a lot of different prices . Also where are good places to list it at for sale . I live in South Carolina .
