I have been trying to find out how to send you a "pm" MDC250, but although I've looked in the FAQs, I can't seem to see the right button to press.
I am in PR4, and although at present not able to wash my car as I'm on crutches, I think it's a very good idea to group purchase, and you clearly have some experience of good products, which I certainly have not!
If you see an electric green, very elderly, SLK while driving locally it is sure to be me, so give a wave or a flash of the lights?
