Glad you like it Billy! The photo doesn't show it that well, but the seats do have those moulded recesses in the back like the earlier BX seats. It just seems to have worn a bit better.
The yellow BX could almost drive itself to that charity shop and back, so often have we visited for furniture items - most of our furniture comes from the place and our clothes too ( priced from 50c to €3)
I've heard that shop referred to here as for 'socially weak' people!

That's fine with me, I'm happy to be socially weak if it means we can furnish our house with mostly 60s/70s pieces that no-one else seems to want as well as 'reducing, reusing and recycling.' We got our complete 1960s kitchen there for €65 ( in excellent state) but that didn't fit in the BX - that required my friends H-van!
