well im only familiar with yakima stuff, but thule makes equivalent, as well as a few more regional brands

but you would need
q-towers
crossbars
q-clips for your car

towers and bars are cheap on cl, keep an eye out for the correct clips used, or get them new, but they are more $$$
then get a set of used racks, steelhead is what i would look for, should find them for $25-50

check yakima site for clip details, then do some local cl searching

also if you want a cheap option hit the local bike shops and find somebodys old used rear rack, should be able to track one down for next to nothing

its almost time to get out the spandex
