Just returned home from my local Poole Mercedes main agent with my failure slip for m.o.t, 2003 SL500, 29K. Failed on the number plates not having the little BS numbers on the bottom corner!! They admitted that the plates were totally OK to read with correct spacings, letters etc., but illegal without little code on. I also paid the usual £320 for an A service and received some recommendations from the m.o.t expert, air and fuel filter £235, spark plugs £359, brake fluid £154, front pads £182, put out an SRS light £220. Not impressed. The brake pads were renewed 3000 miles ago! There wont be a next time there!
