Finally got around to loosing some weight out of the boot! At some time in it's life my car had been fitted with carpet covered hardboard on either side of the boot. Over the years this had gone soggy and nasty along with the black vinyl covering the wheel arches. 2 minutes work to rip it all out and a weight saving of 1.5kg for absolutely nothing!
Amusingly there was also a boot light fitted on the right hand side panel that had been fitted in the past and had never worked. On removing the panel I discovered no bulb and loose wires just hanging down the back!
