Free listing doesn't cover cars mate... 
So its £15 for a classified, or £10 for an auction plus £20 end fee, so you lose even more there.
I totally agree though, £500 barely covers a set of tyres for new cars but that's all a whole 306 is worth. That said, they are getting old now, and not exactly economical, and definitely not cheap to tax (excluding late HDis) which is all people want nowadays.
