its been said already here, but I checked on CR before i purchased too. Oddly enough the edge/MKX were both mediocre on ratings, but 5 stars to the new Impala. With no history. Test drove the Impala, and was not impressed. Maybe a slight bias. KBB and Edmunds (more importantly) user reviews loved the Edge. As do I. Vault like ride (compared to my '07 Taurcedes) SYNC is crazy awesome and voice req makes eveything safer.
2 months into this and couldnt be happier. Just hoping to pull 200k miles out of it!!!
