Value of '87 Coupe DeVille?

Recently saw an '87 Coupe DeVille for sale in immaculate shape.

According to the owner it is a "Classic Coupe DeVille" and is a limited edition with a continental package, carriage top and all the options. It looks garaged, one owner and 66,000 miles.

I can't find this configuration in the Kelly blue book and was wondering if anyone here could put a value on it?

thanks in advance

I paid $1500 for an immaculate '87 CDV with 125k on the clock. It had a new crate 4.1 with iron sleeves. I'm pleased.
