Photos and lots of them !
Clear, close up, and a couple of different angles of each item. Do a walk around of the car including the under carriage, suspension, interior, engine compartment, trunk, etc.. lots of pics. Post them on a photo hosting site like 'Photobucket' and then post a link to them on here when ready. There are a bunch of genuinely honest and knowledgeable racers here who can give you a ton of advise on item worth and saleability.
You might even post a preview pic of the car here while you are posting the rest on a photo hosting site, to tickle some interest.
WARNING !! DO NOT make or secure ANY deals until you gather advise for dealing with unscrupulous buyers and scammers !! HERE is an EXCELLENT clearing house for that particular subject... I cannot stress this enough !!!
LOTS of help available here !! Make use of it PLEASE !!
