Mk3 1.3 S CVT came with the Foam repair kit...Aaagh! Honda spare wheel and Foam insert was huge price. Bought a new (unused) 15" Jazz space saver from Ebay. Big problem...the 'cardboard' boot floor sags with the handbook on it. Made template of boot floor cut to shape on 12mm Ply shaped sides so board would lift without catching wheel arches. Cut a strip of the same ply to fit the gap between the main sheet and the back of the seat. Covered the board (both sides in 4 way stretch van/camper conversion lining carpet (1m x 2m from The Metal House on Amazon £11.99) - used the proper high temp spray adhesive supplied. FANTASTIC! Carpet surface is better than the Honda boot carpet. As the ply is supported front, back and sides on the solid metal of the boot (over the flimsy board) it looks smart and supports a lot of weight. Win win situation - have a spare wheel, the original foam repair can, loads of storage space under boot floor and better carpet finish.
