About 1 mile from our holiday destination with a loaded car last month, yep you guessed it, a puncture! Full size spare in the boot, jack, telescopic wrench and a warning triangle. Had the wheel changed, even emptying the boot and refilling with luggage, and back on the road in <15mins!
I have no idea why all this vital kit is not fitted as standard. We've had spare wheels and tools in cars since they first took to the road. Made sense then, and still do a century later. Omission from spec is fool hardy imho.
