The act of trading, or bartering fills some people with extreme excitement, and others with extreme dread. However, in the current economy, people are turning to trade as a means to acquire what they need. One mans junk is another mans treasure. Food for labor, labor for materials, material for material, cars for trucks, etc etc. If you have it, somebody wants it.
All items, services, thoughts, have a value to them. For instance, I can do basic web design, and also have my own hosting service. I can trade my ability to design a website and maintain it for a vehicle, dental work, food, or whatever based on what my client needs or wants. A lot of people want money, but when a lot of people dont have money, maybe its best to go back to a trading means?
One thing people have confusion over is how to place a value on their items/services for barter. And not wanting to get shorted, or short somebody else. For cars, look around and find a trade value or dealer value, these are good indicators of what your car could barter for. Cash price would be less, usually by 20% or so.
The best place I have found for bartering is craigslist. I usually get emails within minutes of putting something up for trade. Also a lot of areas have started a bartering website for the communities. Look around online to see what you can find.
