Yeah, I'd heard the ST200 had a revised one.
The Mondeo isn't too bad for rust compared to a lot of Fords, but the arches seem to go a bit. A friend of mine used to have a 200, though I only went in it once. They don't feel mega fast, but the way the needle goes round the speedo is quite deceptive really, it did get a good shift on pretty quick, and all without any drama.
They sound nice too, better than the ST220 even. Still look smart too. I'd have one - if it wasn't for the fuel bills!
