It's an interesting, almost philosophical question: why post your car for sale on Craigslist versus eBay? Certainly there's overlap, but the venn diagram is clear.

Craigslist
- primarily local audience
- free and easy to post
- clear distinction between owner and dealer sellers
- no shipping issues
- minimal oversight and rules

eBay
- national and even international audience
- structured postings, better filter and sort options
- fuzzy distinction between owners and dealer sellers
- shipping
- buyer and seller protection, lots of rules

No doubt there's more to it - but the stories should generally fit:
- eBay for rare, newer, unusual and/or higher value cars
- CL for more fungible and/or lower value cars

Other factors can skew it: laziness, comfort with one site or the other, not wanting to deal with callers and people dropping by - the size of the metro area is probably a factor too, with big city CLs covering a diverse enough market that sellers can reasonably go either way, whereas in small metros unless it's a very usual car you might have trouble ever finding a buyer

This is where flippers come in - when a car is on CL but really should be on eBay (or on a used car lot for that matter), and the seller doesn't want to deal with it, the flipper spots it and moves it upstream - if they can resist the temptation to futz with the story and the car, and don't get too obviously flippy about it, none of us will probably mind, and even would call it a service - on the other hand, like with that green peugeot from a few weeks ago, we get a bit indignant

Anyway, that's how I see it from putting a bit of time and effort into this activity - your perspective may vary, and I'd be interested to hear it.
