Merak prices and values

I need to know the approx value of a 1981 Merak. What are the values of Maserati Meraks and where did you get the facts to base the values from? For example sold cars, ebay, etc.

Lets break this into three values

1.perfect condition
2.restorable (possibly running)
3.basket case


Thanks for your opinion
