In my brief experiece of looking at the for sale boards here, compared to two years of buying Capri stuff on Ebay I would be inclined to try here first. Why?
1. No risk of a 99p sale. Now I really like 99p sales, but only when I am buying!
2. If it is a good part it should sell quicker and at a fair price.
3. People seem more keen to fetch stuff, so no wrapping shipping etc.
Ebay is good for stuff that gets bid frenzies, like new/rust free Capri Mk1 front wings, and getting rid of odds and end stuff.
Also on Ebay, if you have got the patience divi up stuff and you will make more. E.g. Cross member, rack, TCA, ARB will make more if sold separately.
