These are exceptionally good quality floor mats. I think the quality is superior to the ones which came with the car. The trim piece adds a lot to the look. I had replaced my brand new ones for perhaps an odd reason. Having recently traded in a car, I wished that I had purchased a spare set of floor mats with that car to save when I traded it as ratty old floor mats can make a good looking car look bad.
Since the ones that came with the Clubman were just basic black, i also thought these would look better with my black Lounge Leather seats. The pattern breaks up the black and it doesn't show dirt as quick as the all black ones did. I also purchased a set of the Mini Rubber ones for the front to use in winter. Should I ever decide to trade in my Mini or should these wear out, I will have the original ones to put back in service. This is the area of the car's interior where wear shows the quickest and which is the most difficult to truly get clean.

Advantages: Pattern breaks up all black interior. Better quality than ones that came with car. Very expensive looking mats that don't show dirt as bad as did the all black ones.

Disadvantages: I can't really find a disadvantage other than the cost. But even though the Mini ones are perhaps more expensive, you do get what you pay for.
