Here is what I carry in my Honda. It covers about half the car's fasteners.
Phillips screwdriver
10mm wrench
I was being facetious because Hondas uses so many fasteners with a 10mm hex head or a JIS (similar to Phillips) head. Haven't had many on-the-road breakdowns with various Hondas over the past 15 years. 10mm wrench to change the battery. Of course we've had a few flats, but those tools come with the car. We did have a '96 snap the timing belt (crappy Chinese belt lasted 50k).are critical fasteners needed to drive the car 10 mm ??
Yep, thats my patrol van
In the past certain jobs were sent direct to the flatbed team (particularly 4x4s) and you might get an RAC flatbed or a local contractor depending on circumstances
Thats changed a bit now, my van can lift all four wheels so if the weight is in limits I can tow them myself
We try to avoid using trucks (environmental compliance)
We try really hard not to use contractors due to operational cost and quality of service
