An internet ad on "car and classic" would be free and worth a go and maybe autotrader? Not sure myself about "pistonheads" but that too has got to be worth a go.
One thing is for sure - you only need one buyer but that buyer might not be sitting there right now with £30K to spend - you might have to wait to find a buyer for a while. Like selling a house really.
@ £30K for such a lovely example is about right i think so no doubt it will sell - just got to find the buyer!
