Best website for selling (newer) cars

[missfire]

In your experience, in terms of results, costs, clientele, where have you all had the best results?

I've only ever used ebay although it can be easy, or a complete fekn nightmare!

Have found, ebay, gumtree (noo..) autotrader, motors, car and classic, facebook etc. But where is best?

Car being sold - new - korean - family target audience - vastly safer but vastly more boring and expensive than a classic audi.

Thanks.
