Whereas the previous-generation Impala featured styling and trim that only a rental agency could love, the current model is attractive, well-appointed and fully competitive in its class. Indeed, it's hard to think of another car that has gone from zero to hero this quickly. If you're looking for a large sedan, the Impala is a genuine must-drive.
