Pricing: Every job is quoted in writing after the free 30-point checkup, and you approve it before any paid work. General service depends on the quantity and brand of oil your car needs; A/C gas filling on whether the car has one A/C module or two; everything else on the fault the checkup confirms. A lighter Essential Service (oil + filter, 25-point check, exterior wash) is the smaller option if you want to keep the job tight.

Four steps, in this order, every time
Diagnosis-first is the whole method: measure, write it down, then price it. It is also why every job, gas filling included, is quoted in writing after the checkup.
We test before we quote
The free 30-point A/C and electrical checkup runs first, 15 to 35 minutes, with a written report of what was measured.
You get the estimate in writing
The report says what was found. Gas filling, like everything else, is quoted in writing after the checkup, and nothing starts until you approve it.
No work starts until you approve
Nothing is opened up or replaced before you say yes to the estimate. If the diagnosis changes the scope, you hear about it first.
Repaired, then checked again
The approved work is done and the car is checked again before handover.
