Set out to clean my roof drainage pipes.
Went and bought a trolley jack (having only just realised that the Zed doesn't have one - and why should it?).
Got back, put wheel brace on all of the nuts one the offside rear wheel. Couldn't shift any of them. Will have to go and see the nice chaps at WG Tyres at Billingshurst next weekend to see if they can loosen them.
Whilst rummaging around in the vast expanses of the boot looked in the largish bag which I assumed held the wind deflector. It doesn't! It contains two of those strange things that fill up the gaps when the roof is down - in original, unpainted black, seemingly never used. Put them on to see what they look like - I was impressed, although I'd never have spent £100 on buying them. So not a totally wasted afternoon after all.
