Hi all i have the mats with velcro on but at the mo i have put a rectangle rubber mat on top which slides as i get in (carefully not rubbing side of leather)i remember i saw a pic of someones car on here and the rubber mat went all the way up behind the pedals.
They have velcro like the standard summer mats, but you take the standard mats out - and store them somewhere safe so that you can't find them when you go looking for them :x
