Thanks Jim. Apologies as I see I possibly posted in the wrong forum. Anyway thank you for the feedback, which is at odds with some of what I've read, but does also makes sense and it's good to hear about the book by Rocky Rotella.
My car is a Californian car. Yes, I'm in Australia, but the car is left hand drive. No problem driving LHD on our roads. It's numbers matching and beautifully restored a few years ago. Came with original sales documents. Hope you like it.
