Just put top bid in and take the prize , its what a proxy bid is , cars worth 7k just put £7,050 bid in an wait ,
Next 10 bids come at 5 to 6 k and you win at £6,100 simples if some one bids it up to 7 k you win at £7,050 still simples , over your top bid an I win still simples . Fight another day .
Only like a physical auction an me watching you and another guy trading bids till one walks and I nick it off you with one wave of £50 isn't it ,
