Which year is this REO, what is it worth?

[ThomasBorchers]

Hello,

a friend owns an early Reo Roadster. It has the 2 Cylinder engine. We are not sure about the year. I guess it should be a 1908. What do you think?

The car is in a good older restored condition. He would like to sell this car. What is a correct price in the US for such a car?

Thank you for your help in advance.

Kind regards

Tom
