Hi - Just thought I'd mention, if anyone is looking for a good buy, my car is for sale on the forum for $17,000 with no money to spend.
Here's the link - http://www.ozrenaultsport.com/topic/30245-metallic-black-2012-megane-rs250-for-sale/
You'd be better off posting a new thread for advice but it's been done to death.
Try searching the forum and you should find all your answers for mods and all other relevant suggestions.
