Fit:
All four mats can insert smooth and flush very convenient.
In the mat on the driver's side two holes of the rubber at the intended (exact matching) point must be herausgedrueckt, can be so that the mat "buttoned in place." The possibly frayed edges of these holes can be reworked carefully by nail scissors to fit exactly to the studs on the vehicle floor after Herausdruecken. Under the rubber mat on the driver's side then (because of mounting) no mat more space.
Among the other rubber mats can leave in principle any existing original carpet floor mats from Mercedes (I have not done). However, the two rear rubber mats are then 2 cm (measured it) shorter. This does not affect the use but also the back and falls hardly on.
Delivery:
Packaging and delivery time perfectly. The mats must before use be separated only in pairs along the intended separation edges with scissors. That's easy. But might (together the elaboration of holes, see above me) but has to be done by the manufacturer of the mats?
