I have had great experiences with this place. I have had them work on several of my cars in the past. They offer the best prices and they do not mark up the parts much at all. They are honest and reliable. You cant get much cheaper than them unless you do the work yourself. Most jobs are done the same day. I usually drop the car off in the morning and can pick up in evening or the following morning. They always clean the inside of the car out and leave a air freshener inside.

Just wanted to say thanks for looking after my cars over the last few years, I've always had such a great service from George and the team and it has been great watching OGS grow into such a successful and prominent company.

Wishing you all the best as always

Just got my car back yesterday, excellent service and excellent staff.

Had my car in to repair the engine, unfortunately I used it for quite a while without oil, and done quite a bit of damage, was surprised how cheap it was to repair and how quick they finished it, I would 100% consider OGS for all my cars future work.

Thank you!

I am extremely pleased with the work and service OGS offers.

The cars I've brought there for work are (and not limited to): 2x Honda S2000 (one is turbo charged and highly modified), Mitsubishi EVO VI, Skyline R33, Accord Type R, Nissan Silvia S15 (drift car), Toyota Trueno AE86 and a few other performance cars.

I wouldn't use anywhere else and I have never had even one problem with them, ever!

Their staff are excellent and very polite, their charges are very reasonable and their level of work is beyond excellent and sets a new standard for the industry.
