Had a scoot with these 2 yesterday.. all pretty high speed stuff on sweeping motorway slip roads...
Results were that the cossie was rapid as you might expect pulling away until his arse dropped on a tight bend and he eased off...
The ST220 though didnt proove to be that quick, I went away round the long sweeping bends but he was catching when it went straight, decided to back off at about 115 as we were going passed other cars like they were stood still...
Anyone ever go toe to toe with a sierra cossie? I feel it may have been a little one sided.
