Whats the bluebook value of a 2 door 1987 Oldsmobile Cutlass Ciera? Where can i find it?

I want to sell my 2 door 1987 Oldsmobile Cutlass Ciera but I cant find a blue book value for it. It has about 100,000 miles on it. Kelly blue book only goes back to 1989. Any help is appreciated|||Nada will give you an idea. Go to their site and go to classic cars for an older car.............md
