Fast Fords have held a lifelong fascination for Dan Williamson, and the RS Cosworth ranks highest of them all. Years spent running a mildly-tuned Sapphire brought all the thrills, satisfaction, and sheer dismay familiar to 'Cossie' owners - from high-speed track spins to roadside breakdowns, there's never a dull day. Dan became a motoring journalist in 1997, covering new cars, classics, and performance machines for magazines including Fast Ford, Redline, and Revs. Despite countless hours in the presence of mighty Cosworths, the hard-charging YB engine still gives Dan an unbeatable buzz. This is his fourth book about sporty Fords.
