Noah E46 factory car cover
This is the Noah fabric car cover sold by bmw to fit all E46's. It fits the car like a glove, with pockets for the mirrors, and a clear plastic window to make your license plate visible. I have only used this cover once.
Noah fabric covers can help protect your vehicles interior and finish from both sun and rain. The multi-layer fabric is very rain resistant but "breathable" to allow any moisture or condensation under the cover to easily evaporate.
Noah fabric is naturally moisture resistant. Snow, rain, dew, industrial pollutants, tree sap and bird droppings are kept away from the vehicle finish. The unique 3-layer fabric construction includes a center layer made from a special, breathable film that acts as a moisture barrier to repel water, yet allow the passage of air. Moisture resistant is not to be confused with "waterproof" - Noah covers will keep the vehicle dry except in a heavy rainstorm or prolonged exposure to steady damp conditions such as accumulated wet snowfall. With time, any moisture or condensation under the cover will evaporate through the breathable fabric. The evaporation time will depend on the amount of humidity in the air and the time of day.
Noah fabric dries quickly and won't rot or mildew. The fabric will not shrink or stretch and resist tears, rips and punctures to provide maximum vehicle protection.
I paid $185.00...will sell for $90+ shipping.
