Don't really understand your comparison. From my understanding the Vue just used the Honda engine. The MDX is larger and considerably nicer than the Saturn.

Consumer guide 'average pricing' for a good condition 'base' MDX is about $13,200, Vs. the Saturn VUE Redline's $6600......
Biggest difference is the extra storage in the MDX because it is a spec longer *Granted the wheelbases are nearly identical*, the legroom and headroom are negligible.
the MDX is a nicer car build quality wise, but for a winter ride I'd never pick the MDX over the VUE
