VOLKSWAGEN is taking on three interesting mid-sized sedans – Mazda6, Liberty and Accord Euro – with its new Jetta. Spanning the $30,000 range and spun off the ubiquitous Golf V platform, VW hopes the Bora replacement’s high equipment levels, unique model choices (a diesel’s included) and freshness will overcome smaller dimensions and an unproven track record. It’s a good deal better than the middling Bora, and the Golf connection equals high dynamics and refinement, but does the Jetta have the elusive ‘X’ factor that all three of its Japanese foes have in spades?
