I'm torn between buying the Mazda 3 custom-fitted OEM winter mats, which look very nice, and the Michelin winter mats from Costco. Apparently the latter is AMAZING, and they work very extremely well. They can hold quite a bit of water because they're deep and they're made of good quality rubber.
OTOH the Mazda 3 mats are custom-fitted and also look really nice. They also look deep enough to hold some water. Does anyone have a set of these, and know how effective they are?
