My friend who has a brand new S4 is trying to sell is Lexus 400. He had a guy coming out to look at it today, and, it wouldnt start! aint it always the case!! anyway, someone else tried giving him a jumpstart, which I would have thought would have started him right up. But, with the jumper cables connected, each time he turned his ignition key, all we heard was a 'ticka - ticka - ticka ... '. Motor wouldnt even begin to turn over...Just this loud clicking sound...Does anybody know what this is symptomatic of? Thanks.
