As I’m refurbishing a G506 Class 325 Fire Truck and finding info has been difficult. That was the case until Mr David Doyle released his Chevrolet G506 book. WOW! Amazing! Fabulous!!! It’s a very large, well laid out and a very comprehensive tome on all things G506. The pictures are the crucial part of the book as I need photos to help with my project truck. There are more models of the G506 than I realized. As a history it’s pretty much the cat’s meow! For the amount of information, the price of $89.00 is very reasonable and well worth the cost. Kudos to Mr Doyle with another job “WELL DONE”!
