I've sold a bunch of ATVs on Craigslist. You get some pains.
Alot of people want to trade you canoes, kayaks, lawnmowers, guns, jewery etc.. then you have no shows. Really can't complain though it's easy and it's free to sell stuff.
Buying stuff on there is harder because old people get all paranoid. If you are that scared to sell stuff then go to eBay. Met some cool people and probably had well over 50 transactions.
You hear about some bad experiences but there are thousands of smooth transactions.
