Impressive, especially considering the Cavalier has been out of production since 2005

To the OP, variety can be the spice of life, but consider yourself lucky in your monotony. As far as the rental car midsize classification is concerned, the Fusion is probably the best-equipped and most comfortable car in that class. I'd take 10 straight Fusion rentals anyday over a mix of PT Cruisers, HHRs and Kia Fortes.
