Is this Marin Fairfax series 1 worth it

This is the sellers description:
Great condition, new touring tires, new cassette, chain, hand grips, brake cables and pads. Original satin black. Other seat will be installed at sale.

I'm an amateur cyclist. I want to ride in city roads. May be like 20 30 kms over the weekend.

The owner quoted 500 Canadian dollas. I'm asking for 400. Please share your thoughts.
