I have an 08 3LT with less than 20K miles and love it. No problems with oil consumption but there are several threads on here about that issue. Sounds like you have been researching the site, so I would say continue looking through them for any other issues between the 07-08.
I ordered my AV and picked it up with about 2 miles on it. Drove until 5K then switched to Mobil 1 synthetic. No issues whatsoever.
Guess you need to ask yourself a few more questions before pulling the trigger besides oil:
What versions are you looking at? LT, 2LT, 3LT or LTZ? Need to compare apples to apples if you're narrowing it down to price.
How many miles on each?
Extras - sunroof, nav, leather, etc.
When was the 07 built? I think some of the early 07's had issues other than oil that were fixed later in the run, but don't quote me on that.
Good luck on the choice.
