It goes through many things from how to service and maintain the car to removing interior panels, headlamps, bodywork etc.
If you want an idea on how much detail they go into have a quick look through other cars Haynes manuals in Halfords or motorworld.
Anything specific your after? I could look it up in my manual.Then again if it can be done to a Clio - theres bound to be someone here whos already done it and could help.
Zydered: This manual for May 98 to May 01 Clios hasnt been out long, so in theory Mk 3 owners may have a couple of years to wait till their manual is published
