Our Thanks go to Kristian & Mary from K&M Performance for giving us the opportunity to take over the workshop, and from the feedback so far, we seem to be kicking some goals.

One of the great things about Lithgow is the support and inter-action with other businesses and we find out very quickly who is fair dinkum or not. One of the places that we can sincerely recommend is the people at R&A Chainsaws at 327 Main Street (big yellow building opposite the Servo.)
