Radiator has been weeping for a while now so finally got that replaced and fitted a Spencer Ashley metal T piece - no more coolant whiffs at the traffic lights. Whilst the bumper was off I also fitted a 500Hz Hi-Tone second horn. She now honks with real purpose, presence and regality
If anybody is still harboring thoughts about fitting the second horn then just do it. Best upgrade I ever did... I also have a low-tone going for postage if anybody needs one
