Chased up Toyota today Excel and Dynamic model if ordered with the panoramic roof you do not get a spare wheel just a repair kit, apparently it is all down to weight and emissions, however the 2 other model will come with a spare wheel, alternatively you can just order a spare wheel.
I had the same problem, - no spare because of the Panoramic roof, and no one at Toyota could provide a solution. I eventually found an online supplier - thewheelshop.co.uk I bought a complete Spacesaver wheel and jack kit there for £165, they also do steel wheels and winter tyres for most cars.
