I have been driving around in my Mum's 05 Megane Sport Tourer (1.5 DCI) and I found it quite a competant mile muncher. Been getting 66ish mpg out of it, and thats through towns, A-roads and motorway driving.
Sure its not rapid, but its not horrifically slow, and its very comfy to drive long distances.
Handling is not amazing, but it was not scary to drive quickly on B roads!
Renault admit that the 1.6 engine is absolutely **** though lol
It was what the sales person told my parents got rid a 1.6 scenic for a 1.5DCI megane sport tourer
