Ah right....Supose they will always go high to make putters hink you could get a bargain...
I find that when you see a car your interested in , from the picks work out roughly what you need source and price them , 247 spares is good for late run of the mill stuff, specialist cars you need to know the people that break high end stuff , but at the same time work on new price parts , if after all that they are both below 40% of the value then its worth a physical look , and an exact parts list and price up to enable one to bid accurately and not screw up, after a while you get to know what things cost to make a judgement call
