My wife and I live in New York City. For most people, this would mean no car, but our neighborhood isn’t on subway lines, necessitating wheels for errands, and we often leave the city on day trips. Our car – a ’98 Jetta – has needed nearly $2,000 in repairs over the past 18 months (and repairs are necessary, at an increasing rate), so it might be time to move on. We both agree that the best car for us is a Mercedes-Benz GLK Bluetec (yes, we test drove the previous generation), but that’s more for when we plan on moving out of the city next summer. We sorta need something until then. What are our options?
