I was amazed tonight ! Looking through the net and I found a reference to a report in Car Magazine, May 1987. A test report of a BMW M5 v Commodore V8 v Sierra Cossie v Merc.
Bugga me the pics of the Cossie are my car !!
I've found the magazine in a vintage mag shop in the States and bought a copy.
I feel like a kid in a candy shop.
I havn't read it all yet but thats what I'm off to do now.
Great day today !!
Cheers
Keith
