The Enclave and the Acadia are the same vehicle, aren't they? They're built on that same Lamba platform. This Fall, Chevy is supposed to have it's equivalent on dealer lots: the Traverse.
I'm going to be buying a new vehicle at the end of this year or early next year. It'll be a GM product for sure because I have additional discounts that make other like vehicles look way too expensive. Right now, it's the Acadia or Traverse versus the Uplander. I already own two sedan cars and plan to keep both, so I'm looking for something with a little different utility. The Acadia (and Traverse) are easily the more exciting vehicles in every way, shape, and form, but the additional up-front cost and gas bill might ultimately make the Uplander the winner. With GM closing them out this year, I'm sure I'll be able to get a better deal on an Uplander. However, the Chevy Traverse might be less expensive than the Acadia, closing the window somewhat. Still, these XUVs are not "small" vehicles. I believe they're around 500lbs heavier than an Uplander (but, interestingly they have smaller engines than the Uplander - 3.5 instead of the 3.9 in the Uplander).
What's your gas mileage like with the Acadia? I think I remember seeing ratings something like 19 city and 23 highway? I think the Uplander is very similar, but as I said the up-front cost should be a lot less...
