Most trustworthy mechanics I've ever dealt with.
Talked me through everything completely, described all the best options and helped me come to a decision which benefited me most, and not him. Best part of it all it ended up barely costing me a cent. Bought them a bottle of wine because they refused to take more money for their work and advice. Would rather drive to the other side of town to use this mechanic rather than any of my local garages.

Approximate cost: $Bottle of Wine
