I have a hitch for my Subaru and nothing could be easier. But... since you said you're not ready for that I can recommend the Saris Bones . We use that on our other vehicle. We tried many other ones (our local LBS was generous enough to let us return those that didn't quite work or fit as we wanted) and I found many had arms with very limited ranges of adjustment. The Saris allows you the "dial-in" the fit for both your vehicle and bike.
