Yep. But I don't know what the Aussies did for a spare. Personally, I wouldn't have minded having the gas tank stay in the same location -- and have a can of goo to fill up a flat. Oh, well.
Suggest you visit the Crossfire forum and do a search on flat or flats. The XFire comes with the Goo and a compressor. If you pick up a nail, that's fine. Our low profile tire, and even lower profile on the XFire tend to blow out sidewalls, if they hit a pothole hard enough. A barrel of goo won't help you with that.
At least our tires our more commonly found. The XFire tires are similar to the Vette's. Can't tell you all the horror stories I read on that subject over there. People stranded for 3 days, and then screwed for $800-$1200 to fix a flat tire!
I've also read the new Solstice has the goo, too! :rofl: And if you think our trunk is small, check out the Solstice. With the top down, there is no trunk.
The spare in the trunk was one of the things I liked about the GTO.
My 2 cents.
