Hi all, i'm a newbie here. Have driven mercs for the past 4 years and my recent 04 plate clk cab is boring me. Also Merc customer service is sh*t. I saw an S4 in black parked outside Tesco's Northampton last week and fell in love. I've also seen on the net the 400Bhp S4 that Milton Keynes Audi have. I do live in MK and might go and see it. Anyone have any advice on the new S4 ? I have been consider the new Merc C55 AMG but feel the £48K price tag a bit steep considering i can get a new S4 for £34K. Matthew.
