Although cars are more reliable than ever, tyres still get punctures, bulbs fail and sometimes even the most dependable machine comes to a grinding halt. Chances are, too, that these things happen at night, in filthy weather, miles from home.

You could spend hours compiling a list of must-have tools for the boot,but why not invest in an emergency or breakdown kit instead? These usually contain a foot pump, tyre pressure gauge, torch and a decent wrench that will loosen even the tightest wheelnut.
