Thanks for the invite. If iv'e found what im looking for by the end of October then i will come along.
Go along even if you haven't, you'll pick up lots of invaluable information.
Is it a metallic thumping or otherwise? May pay to check your tyres too, make sure one isn't delaminating. Disturbing noises should always be checked out as soon as possible. Say it is a tyre or something else and it goes, at speed.................
Your charge outs over there are so high. Pay that in Kiwi $, so 250 UK clams.
ps. Edit, how many hours are they charging out, aside from parts/oil needed?
