I dunno about the current price, Smed, but I have had that book since it was first published.
In the '60s as a 15 year old wannabe, I haunted the Sydney Showground Speedway every summer Saturday night, I loved the Solos, Sidecars, Speedcars, Supermodifieds, now known as Sprintcars, in fact all of the proper racing machinery, didn't think much of the Tintops, the Sidecars were probably my favourite Division.
I still refer to Jim's book at times and it's a great read, with top photos,for any Speedway tragic, Ohh, yeah. My first date with my wife EA, was, guess where !! Yep, the Showground Skids !!
