http://www.importfan.com/ has a couple of body kits available.

There's also a guy on eBay who's been selling R34 style bodykits.

Personally, the only Vigor body kit I've ever seen that looked good on the car is this one, but I don't have any idea what kind it is, or where it might be available.

Unfortunately, your friend will probably find that aftermarket support for the Vigor is a bit limited. Good luck!
