Yo dude...so your looking for a roof rack huh.....cool, I know lots about roof racks.
If you want the best kind, your gonna want to go Thule
www.thule.com
Thule works with every manufacture to specially design a kit for your car. The initial setup isnt cheap...300-400$ cdn.
Second choice..Yakima there the closest in quality to Thule..cost a little less...but you can only use Yakima stuff on there setups..becasue they use round bars, but there equipment is decent......
3rd choice-----only if your tight on cash..........Sport Rack.......there cheap, but affordable...they dont hold alot of weight...and dont go on nearly as neat onto you car as Thule.
If your looking for a killer bike holder go with SportWorks Bob Ratchet.....holds any bike made out there...and the easiest......30seconds or less!! BAM , they also mount onto Thule bars. I have 3 of them.
Thules big mouth is good too,
Then you'll want an airdam,, they cut the wind noise...and its good place to put stickers
Well if you need to know anything else just ask, But check out the Thule web site..its awsome
