The Sentra is approaching the Cavalier/Sunfire mark for dated appearance, and incentives. At least they are cheap to buy. I think the Quest has its issues as well. I figured the X-Trail would do well - it's a great package. But Nissan still have some tweaking to do to reach Toyota/Honda levels in perceived product quality, where they don't have to undercut their prices to compete like the domestics do.
But hey, things are certainly looking up for Ghosen's crew.
