I had one as a company car back in 2000 (w reg) for 12 months. As a fast road car it was 100% better than the vectra gsi i had before it (not hard really..)
They are quite hard work if your just in the mood for pottering along, but if your in the mood you can wind 'em up something rotten !
I had one in pirates black (the very dark purple colour) and it looked mint. The downside was every twat in a corsa/saxo etc wanted to race you all the while.
Plus it did like a drop to drink, but as i had a fuel card i didnt give a fook! But it was averaging about 22mpg.. But i used to cane it everywhere.
But i'd buy one again if i was in the market for one. Nothing ever broke or fell off it, and the dealers seemed ok as well.
Buy one and enjoy it - they make the ST200 seem SLOW !
