I'm sure there was a decent comparison a few years ago with lots of Hot Hatches inc. 172 and ZR or maybe ZS. They were very close on the track, in the wet. The Clio was the quickest overall, beating the Civic and Astra etc...might have been an Autocar review.
Personally, they look okay from outside but the interior in ZR's are rubbish. No contest for me - no matter how close the performance is.
I think I remember the one you mean as well mate - was a green ZR iirc and they said it was good value etc, but the interior was just cack?
On the HG issue - there's some uprated bolts and stuf available to cure it isn't there?

Yep I'm fairly sure there's a few places offering aftermarket upgrade kits for them now. Makes them quite a good engine then I think, it's the same old british engineering story of good product with an atrocious achilles heel!!
