I've had 50% success. The convertible did not have one, but the silver TT did. I'm using a 280ZX pump in the vert.
i have not got one - i just rely on not getting a flat? i have a can of goo/compressed air stuck under my back speaker for justin - would probably end up calling nrma first tho...
They were put in there because two seaters come with a deflated spacesaver spare, rare-ish because they seem to get lost or go missing when the car changes hands, apparently they're pretty good little pumps...
