Jim not fitting into your car is pretty much the worst reason ever.

Wrong.  It was the main requirement.  And it was what I wanted to do, so that makes it a perfectly good reason (for me).
I wasn't going be hauling my bike to work on a bike rack on the roof of the car and leaving it in the parking garage all day, wasn't going to have $X,000 worth of bikes on the back of the car parked overnight on the streets of Washington, DC or New York City, and wasn't going to be hauling them through the road grime if I decided to drive some distance.  I know lots of people use bike racks and roof mounts, I wasn't going to.  At 60+ years old I never even considered the idea of lifting my bike off/on a roof rack at the beginning and end of every ride, and trunk racks just look like a good way to let one bike bang around and damage the other.
With my RAV4 or Lynn's Honda Element, we could put all 4 bikes in the back (we usually only have two) and still have room for luggage. My main reason for purchasing the RAV4 was because the spare tire is on the rear door resulting in a taller load area. (The other factor was the V6 engine in a smallish vehicle performs quite nicely.)
So, it may not be high on your criteria, but was on mine.
