I discovered OGS mechanics a few years ago from a online review and I’m sure happy to give my opinion about them.Most garages will try to quote you for work that may not be necessary and start talking technical.I find OGS people are simple to deal with and honest.Just had an annual Mot and service done and the guy deducted some amount off from the quoted price because the sparks plug was fine.I had other positive experience with them before as well.Some people seem to have an issue about some staff doesn’t speak good English,hey they speak perfectly good English for me to understand.Its not easy to find a honest garage these days.
