My fiance and I just bought a 2011 Specialized Ariel Disc and a 2011 Specialized Crosstrail Disc. We are looking for a non-hitch, non-roof rack bike rack that would fit both our cars (a 2011 Subaru Legacy Sedan and a 2009 Subaru Impreza Outback Sport). What bike rack do you recommend? We are based in CT and plan to drive to nearby and regional trails without having to worry that the bikes would fall off or scratch the car. It would be great if the rack would work for both cars and we won't need to remove bike tires or anything. Basically, make it as easy as possible, but still be great quality.

Budget is less than $100, ideally $50. Thanks!
