Long term feedback on work done

This is some long-term feedback on work done by Bert for me. I had a Ford iKon 1.6 with a blown headgasket. Bert overhauled that engine for me. I also have a Nissan hardbody whose engine i had overhauled through a different mechanic and I can confirm that Bert’s work was of a much higher standard. I have sold the iKon to a work colleague and have kept tabs on the car. 4 Years on and that car’s engine is faultless and my colleague is still very happy with the car. I still have the Nissan and its engine was never the same and is in dire need of another overhaul. I will be using Bert this time to do the job properly.
