I think the US distributor listed in previous posts has folded. There might be a new one. Shoot an email off to
sales@rola.com.au as they were the ones that got me in touch with a US distributor a couple of years ago. There are also tons of AU and NZ sites that carry Rola Roof racks. You may be able to find some that ship to the US. If not, try to contact some of the AU members and see if they can help you out.
Your other option is a Barrecrafters roof rack. I think there is another thread right now with some pics of it on a SVX. I prefer the looks of the Rola Roof rack as it doesn't use as many bars to attach it to the car. A much cleaner look from my perspective.
Let me know if you need some pics.
Cheers,
Matt
