Thanks for all your help and suggestions.
Last weekend I bought a heavy duty 7x4 trailer with high sides, from
Mario Trailers.
With a bit of rearranging in the garage, it fits in the second car space so it's out of the weather which is good. My car continues to decay out on the driveway each night
Now just need to get some tarps and ties and occy straps and ropes for the much anticipated first use!
