What do you actually want to know, Freaky?
I can tell you that he's got heaps of experience and really know's his stuff.
He's had heaps of racing experience, did the GP's with Andre Bosman & Dave Kellett, is seriously clued up about TZ's, ran Pitmans workshop in the 70's/80's and is now a Husky dealer.
He was my mechanic for 3 Safari's and paid most of the bills for that too.
So it depends what you want from him as to whether he's the bloke you're after.
P.S. It's just Trev Otto. I don't think his Mum even called him Trevor.
