I'd say photos are poor because of bad location, other car and bloke in background create the wrong impression compared to most private V6 clio adverts that use scenic 'much loved' pictures
Even fresh photos will help
Take closer pics that show the full car but also the condition of the paint can be seen
Looks like it needs a good polish, tyre gel etc
Sentences like car has done xxx miles engine has done xxx miles put alot of people off straight away
Avoid too much info about power etc, a genuine buyer will ask the right questions if interested
Just be factual and give the all the big bill info about the car, cambelt, discs/pads, tyres etc etc all the expensive stuff
As other people say get the mesh sorted out and spend a couple of quid on centre caps
Just my opinion and initial impressions, hope its of use
