Got mine last month from Holdcrofts £85 delivered.

Though seeing in the boot is nearly impossible I have a small pale holdall with bits in it like a foot pump and a torch I sometimes need at work and this could be seen.But I cunningly disguised it with a black bin bag,and now it blends into the dark nicely.
