I can tell you this, as another mechanic I really dont look, if itys out of place I look, if its insuffecient or over kill I look. Organized and workwise I look, fussy cleanliness not so much unless the job demanded it.
One of the top truck shops here is a pig pen, he has a lot of that truck stuff but its buried in rubble. I do use him on my inspections at same or higher cost that the shiny outfit. If him and son can work in the mess more power to him, despite that he knows what he is doing and second knows I know what I am doing and if there is a minor issue he would like to see corrected he knows it will be done asap. He wouldnt be scared to tell me something was wrong or right knowing it doesnt benifit him 50 cents either way.
In this respect the tool is of no concern to the service, both shops have same tools and boxes, one is cleaner costs a lot more, always trying to upsell something like I just fell out of a tree when I am there to get the paper.
As a side to this the messy guy is the master mechanic of record for last 30 yrs at the truck garage, he asks about my strawberries and if there was ever a mechanical issue would swear on it had to be human error vs neglect.
If I wanted to drive a Mercedes could probably do it with a 10 yr old one I made a diy deal,,, if I really could afford it probably do the same, take to dealer on occasion and call it a day. The Ford dealer gives a service deal that cant be beat, well under 30$. My neighbor girl bought a 40K truck she dont need and has to work to support and in dripping winter out under it doing an oil change it dont need to save 5$ on materials. Ha.
We have a full shop, buy on sale, I got no problem if Dad wants to pay the 26 to go down and BS while they change the oil and do the fluids tires, they even wash it. I will get up from this keyboard for a lot of things but to save a dime on that one aint it.
We live on rugged roads, at that rate willing to let the dealer do the general lube on untill it starts to need service work, As they come off warranty and times/years/seasons become a factor we assume the service and do routine as they come in for other issues.
Got a pickup in now that was 8k since oil. some in a dusty world. It had been in earlier for muffler at 5 or so, we greased the front end, we didnt figure to run it another pull before its yearly but we 2 new tires to it and fuss with brakes, change oil, I got it on once a year for oil, dont care if its 3 or 4K or 10, dont even look at the odometer untill it comes in. If we brake down a unit or 2 you can see the miles go up on the rest, its fleet service type numbers etc. I got a couple trucks change at 5 yrs.
