How can mechanics and garages use AI?
Short answer
UK mechanics and garages can use AI to explain repairs to customers in plain English, write quotes and estimates, send MOT and service reminders, answer booking calls, reply to reviews and chase invoices. AI can suggest possible causes of a fault, but it can be confidently wrong. Diagnosis and MOT results must come from your own inspection.

How mechanics can use ChatGPT
"Explain to a customer, in three short sentences and no technical terms, why their front brake discs and pads need replacing. Mention it's a safety item and the price is £X."

Limits
Don't paste customer names with registrations into a personal chat account. Never let AI decide whether a vehicle passes an MOT; follow the DVSA inspection manual. Treat AI fault suggestions as a list to test, not an answer.
