peugeot us express hybrid bike

Hi all, I am new to this Forum.

I have a Peugeot US Express Hybrid. 1990

It is old but has only been ridden about 10 times.

I am looking to sell it. I just brought it in for a Tune up and it is in good shape but I did not purchase anything new for it.
Does anyone know a great place to put it up for sale.

Thank you and have a wonderful and safe day!!
Carol
