Luckily, I don't live anywhere near that set in NJ, so I'm a little less perturbed by the BMW. OTOH, my mother once drove an X5 for a few years and couldn't wait to get rid of it. Too flashy for her taste, and too close to the country-club aesthetic in her town.
My own steed is still an '04 Saab 9-5, which suits me just fine. There are a few things I'd like to improve on it, but nothing I'd pay a lot to get rid of. If I were to get a replacement, though, the new BMW 328 sedan is looking interesting. Bigger than the last one, it actually has a back seat that humans can use. (I have a nearly-adolescent son, so I have to think about legroom there.) And it's not so big that I couldn't drive it in and out of a Boston parking garage. I gather the ActiveHybrid coming out soon will be interesting for a number of reasons. Or the xi. [ I wonder why carmakers won't offer diesel or hybrid AND AWD on the same vehicle? A lot of New Englanders like both fuel economy and winter performance with their luxury.]
Other than that-- dunno. The Audi A6 is certainly aimed at a family my size that has to deal with winter weather and road trips. Perhaps too big for commuting. And as boring as the Lexus ES is, it has a certain buy-and-forget-about-it value. Also the quiet ride would make the stereo worth paying attention to.
On the other hand, when I look at all these cars, I can't help thinking that for the cost of one of those I could get 2 or 3 really fine antique French violin bows. So the Saab stays in the rotation.
