Never heard of the box issues myself - have heard about the mounts being shit. Replacement is easy and cheap - powerflex 'dogbone'

Seat belt/Airbag light is common and easy enough to resolve.

Any sounds of whining coming from the front left as you look at the engine mean the dephaser/diverter pulley is on the way which when it goes WILL take out the cambelt/engine.

Other than that nothing major- just use and abuse as you see fit.

Cliosport is their home and a good site but you have to pay - I know.... they obv don't get that the internet is for free!
