I do make a living out of diagnostics but at a much higher cost (investment) than say a mate of mine that only specializes in fitting truck and tractor tyres. Specializing in diagnostics when you are using your own brain is one thing but making sure all of your franchises are up to the mark is another especially when your company name is on the side of the van.

Lets put it another way "what do most franchises have in common?".

Well its simplicity be it flipping burgers to doing smart repairs on alloy wheels.

There is a Begining a Middle and an End mostly at set prices be it a £1.99 burger Or a £50 alloy wheel repair nationwide (franchise advertising).

E.G Begining.- customer asks for burger.
OR can you repair my alloy.

Middle.- You cook the burger and serve.
OR you repair said alloy.

End.- You get your £1.99 for burger.
Or you get your £50 for repaired alloy.

Even the franchise outlay is defined I.E to cook burgers you know you will need a cooker and frying pan etc and you are in bussiness all over the land. Smart repairs paint mixer, spray gun etc same equipment to do the same jobes be it alloys on a wheelbarrow or Ferrari!

Same for all franchises Tyre fitting, windscreen repairs, Window cleaning to drain jetting the list goes on.

And to your question of the mobile hometuners of the days gone by. The work was defined.

Begining.- Can you tune my car?
Middle.- car tuned.
End.- Pay for the tune £70 or what ever it may have been.

Hometune Franchise outlay Defined, A Van And A Crypton type Tuner (Which did most if not all the cars it was ever going to see).

Jobe Done!

Now tell me is vehicle diagnostics on a franchise ever going to be that easy or defined?
