Hi Adam -
Do a search on here for roof rack and a few threads should come up. If I remember right, there was only 1 or possibly 2 brands that made SVX compatible racks - neither of them the 2 common ones (Yakima, Thule).
One was Rolla(sp?) I'm pretty sure, and there may have been another. I'm also pretty sure both companies are either a)out of buisness or b)no longer have the SVX rack. As far as I know, the only way to get one is to happen upon a used one, very rare!
There have been some SVX owners that have put a fairly discreet hitch receiver under the back bumper, and then were able to use bike racks, etc that go in a receiver hitch (one actually even used the hitch to tow a motorcycle on a trailer cross country).
Like I said, do a search, I'm not totally up to date on the subject, maybe by now someone has figured a way to make the newer rack systems work.
BTW, welcome to the site and SVX ownership! If you are interested in meeting other owners and doing events, check out

There's actually an event coming up next weekend that should be a lot of fun.
