DIY induced problems so far this week.
One thermostat in backwards cooked a BMW.
One used radiator(very leaky) cooked a Peugeot.
One attempt to force into gear with broken clutch cable(engine running)ruined a gearbox.
One wheelspacer lost immobillised a Fireblade, bikers do it too!
I'm sure there where others and will be more next week.
