Not bad, installed in a Megane III grandtour which has almost the same cabin as the regular one, they don't smell like plastic, but rather a scent.... which gradually fades away. The support bases for the car mats in the driver's position are two, while the mat has only one slot on the left side as you sit. I had bought carpet mats which fit perfectly for the regular one as well as mine. They just wore out after a year and a half, so now I chose these. Only time will tell.
