Your bigger concern is not whether a bike will fit, but whether you can still find a car in a manual.
Short of a tiny econo box, you should be able to fit a bike in the back of any car with the seats folded down. Fit fine in my Fusion, fits fine in the fiancee's Cruze (we can actually fit two in the back of both), and used to be able to fit a single bike in the back of my Mustang.
