Me mums got a 1.5 dci Megane and I think its the nuts!!
We both drove from Brighton to Plymouth at the same time last year and I used a whole tank of Optimax on the journey and my mum used a whole tank there and back and using the car for the week she was there!
It drives nice as well coz you dont feel the need to floor it everytime you get in it!
lowered 35mm (damn it needed it!!) 17" cesam mygale gunmetal wheels, optional renault spoiler, colour coded bumpstrips, renault clear lens rear lights, green cotton panel airfilter, superchipped and a partridge in a pear tree! im looking into getting an exhaust system soon. working on the theory the more you put into and engine, the more you need to get out!
