I have an Evolution 'small 4WD' car cover that fits the RVR perfectly. It is weather proof although quite soft and does not mark the car. I used it about 5 times to protect my RVR HSG between waxing it and events like cruises and my wedding. I paid $140 when new.
Happy to trade it to a good home for any 6 pack of decent beer as I no longer have my RVR.
If I have to put a price as per forum rules, $20.
Pick up Brisbane. PM here if interested.
