You always know its a scam on craigslist when they dont list their location.
The most recent scam on craigslist I saw was a 99 BMW 538i silver in pristine condition for $2700. The guy did not list location, made me tell him mine first, and then said the car was in Texas and he would ship it to me for 200 bucks. So, after that, I volunteered to pay for a plane ticket (my dad's a pilot and I can get them free) and fly down and meet him rather then buy sight unseen. Then he emails me back saying that he is currently living in the UK and that the car is already at the shipping company. I said I would get a taxi and drive out to the company. No emails back yet. I was skeptical at the very beginning, but it was funny how far he took it.
