WE may have laughed at Kia’s previous mid-sized offerings – the medieval Credos of 1998, followed by the invisible Optima duo sold here sporadically since 2001 – but now the South Koreans are deadly serious with the Magentis. OK, so it’s a Kia with another funny name, but only a fool would ignore a pleasantly presented medium-sized sedan brimming with an alphabet soup of safety-related acronyms – including ESP – and a load of standard features, all for mid-range small-car cash. And did we mention the new five-year warranty and upcoming Magentis CRD turbo-diesel for under $30K?
