Carcoon Evolution Outdoor Size 2, perfect fit for classic Mini.
Dimensions: 320cm x 150cm (10'6'' x 4'11''). Battery charging included.
About 4 years old, used only intermittently, kept the car dry, snug and ventilated in wet/windy weather. Good condition. No cuts, tears or other damage. Base has tyre marks and light oil stains (it was a Mini after all). Top layer has creases from being stored folded. Everything works fine.
The consensus is that the Carcoon is the best storage system for keeping rust and mould away. This outdoor version has double-layer bubble with insulation and UV protection.
Cost new is £446.
£200 if you can collect from London W4 (Paypal or cash on collection). I will box it up and send it for £25.
