Just the normal 20 oz hammers for me. I used to have one with a fiber glass handle... until it snapped!
I now buy cheap draper or rolson ones because hammers are like pens, tape measures and calculators... they always go missing!!
BEST - Buying my 110 a couple of months ago and putting extra seats in the back for the kids (I convinced the missus a Land Rover 110 was the only vehicle big enough to fit our 4 kids in ). Also getting rid of the 2.5 petrol engine for a 300 tdi.
WORST - A sticker I bought off ebay which ripped off after the 1st jet wash
