yeah. go to thule.com
, figure out what parts you're going to need. then get as much of that off of ebay, and get the rest at a local shop. you'll probably have to order the fit kit for your car, but everything else (aero feet, bars, ski carry thing,) you can ebay.
if you've got a car that already has factory roof rails (i.e. subaru outback), then you're going to need different stuff.
i've got like $500 into my thule stuff, because i've bought it all new. then again, my setup fits all three cars my family owns.
and to get around the gas mileage (sort of), spend the extra money on a fairing. that SERIOUSLY lessens the gas-impact of the rack.
