Nathaniel was great! There had been a mix-up with the wrong part ordered, which he sorted, which meant a slight delay and kept me up to date on that. A quick job completed successfully. Personable and friendly (and convenient!). Would recommend.

Paid for a engine diagnoses oxygen sensor at fault. I paid to have them changed early June this year. At local garage. Machanic told me to take it back to garage under complaint. Doing so

Reply from Nathaniel:

Thank you for your review, Michael. I’m pleased I was able to identify the fault and advise you on the appropriate next step with the garage that recently carried out the repair. For clarity, the diagnostic report was submitted through ClickMechanic shortly after I completed the inspection, so it may unfortunately have been missed or filtered. If you’re unable to locate it, I’d be more than happy to help ensure you receive a copy. I wish you all the best in getting the issue resolved under the previous repair.

Great service, good communication and a thorough inspection.

Both phone communication and the report were thorough and punctual - Nathaniel provided options for further diagnostics upon discovering a small issue.
