Each role concentrates on two of the six services. The emphasis is the same across all four: safe diagnosis, a written scope, and approval before any added work.
Owner and lead technician
Leads diagnostic and repair-versus-replace work with a written account of symptoms, observations and options. The role separates what is known from what still needs measurement and does not promise a repair result before the car is inspected.
Service coordinator
Turns enquiries into useful job notes by confirming make, model, mileage, service history and the behavior being reported. This role explains the next response window without advertising round-the-clock or guaranteed emergency recovery.
Senior diagnostic technician
Concentrates on engine diagnostics, scheduled servicing and the condition of the drivetrain. Each job follows a consistent sequence so findings can be explained clearly instead of reduced to a one-line recommendation.
Brakes and suspension specialist
Focuses on braking performance, suspension wear and the noises that arrive with them. The role uses measurements and service history to help distinguish wear, damage and adjustment before suggesting a path forward.
One technician stays with one car from the first reading to the handover. That is why work is booked against a scope rather than against an hour.
Readings first, written down and shown, with the options set out before anything is fitted.
An email when a service interval is worth a reminder or a recall affects a common model. No fixed schedule, and one link in every message removes an address from the list.
It is published in the open, where anyone can copy it, so it is left short of its final polish and audit pass. The design chosen is fully audited and polished before it goes live.
