What schema to use for a classified ads site item?

I have a classified ads site at www.gastonia.com.  We are redoing the
site to be HTML5 compliant as well as incorporate microdata from
schema.org to represent the items for sale on the site.

Given that these items are used and that they are posted by different
people, is the Product vocabulary the correct type to use for them?
www.schema.org/Product.

The reason I am confused is that the Product items can have a
'condition' data time (newcondition, usedcondition, etc) as defined by
the schema.

Also, you'll note here that under the usage guidelines the fact that
this product must be available for sale directly from the page without
having to contact the seller. But, the seller can be an individual
(discussed later on.)  If a seller is an individual, and the item is
used, 9 times out of ten this product is going to be found on a
classifieds type website. Otherwise, it would seem that the Product
schema was built specifically for ebay, and maybe amazon's used
product area.

So, is it ok to use the Product type here? If not, what is the best
vocabulary for a used item on a classified ads website?

Thank you,

Blue Presley
