Jetta is close to the Passet in terms of price. Personally I'd pay the extra and get the Passet which is bigger and has more of a quality feel to it.
Or consider a higher specced bit lower priced Skoda Octavia, it is built on the same platform,running gear and has the same engines as the Jetta but always comes out more reliable in the various surveys
