I'm not even sure where to begin with this question.
Ok... I have 1/4", 3/8" and 1/2" shallow and deep socket sets 4mm to 34mm
with 3 standard ratchets and one 3/8" drive and one 1/2" drive long flex head ratchets.
Plus lots of extensions and UJ's. Set of torx sockets.
Full set of combi spanners 6mm to 32mm, loads of screwdrivers, various pliers and
cutters, hammers, tape, fuses, rags, small trolley jack in a case, a spare battery (really),
emergency light, foot pump, one litre of oil, punches, drifts, vice grips, automotive multimeter,
wire brush... and countless other bit's and bobs.
I realise it seems a bit silly to have all that in my car, but since I was 17... that was the kit
I did all my servicing with and the repairs I could. It's only been the last 6 years that I have
had my little home workshop and fully kitted it out. So I leave my old kit in the car... You
never know...
