I always look at Ebay classifieds first, lots of room for a write up and pics, plus you can look up the seller's feedback to give an idea of who you might be dealing with, to me as a buyer ebay is best.
Maybe take some underbody pics of the chassis etc, few people in this country do this but its quite common in other countries, if you're motor isn't rusty underneath you'll save yourself and potential buyers wasted time.
