If you want to change the seats, bucket seats are around half the weight of the stock seats, at least 14kg to be had here. Not a cheap option.
Could dump the misses and take the passenger seat out, good 14kg+ saving there
Floor mats? get them heavy fuel eaters out!
Cone filter instead of airbox, 2.5kg
Cut sugar from your diet and walk an extra 20mins a day, might be some weight saved there. But then you could be a 0% fat road cyclist for all I know.
Only wear race boots when driving, every kg helps so leave the doc martins at home.
Run with the screen wash only half filled. Have to top up more quickly but it's another 2kg saved.
Add all the ideas in this thread together and there is loads to be saved
Just added them up.. 97.5kg of savings! about the weight of a larger passenger.
