I'm wanting to buy a megane cabriolet (it'll be 2004 onwards). I was after a 1.9 diesel. But there's not many of these for sale, so I'm thinking of getting a 1.6 petrol and remapping it, as there's a lot more 1.6 petrols for sale. I just wondered if anyone has had their megane remapped and what extra power they go out of it?
Also, are there any common faults I should look for before puchasing my Megane cabriolet?
Thanks

Lauren
