The world's first totally transparent mechanical workshop has been opened, where everything can be viewed live online as it happens.

The mechanic gets filmed as he's working the car, so that every part that comes out of it, and every part that goes in, is recorded.

George and Jean Alim are the brains behind the world-first - a revolutionary set-up bringing complete transparency to their suburban workshop, called U C Us.

"We saw your report where you had hidden cameras in some cars and had taken it to a number of different mechanics. That's when George came up with the idea," Jean said.

"It's the world's first totally transparent mechanical workshop where everything can be viewed online as it happens. The mechanic gets filmed as he's working the car so that every part that comes out of the car is actually filmed, everything that goes into the car is filmed," George said.

"They're not going to get told that their spark plugs are being changed and they're really not; or that there are new brakes when they're in fact second-hand brakes; or that a mechanic's spent six or seven hours working on a job when he hasn't really opened up the bonnet."

There are 25 cameras positioned around the workshop to cover each bay and close-up vision can be viewed live by the customer on a smartphone or computer - and you see only your car, no one else's.

Customers are also given a DVD copy of the whole repair.

George and Jean's garage is in Sydney's Brookvale, but they plan to set up more and in other capital cities soon.

And the nice addition is that the service isn't more expensive than normal, with the extra peace of mind not costing any extra.

The U C US Mechanics special offer for Today Tonight viewers means you can have two cars serviced for the price of one if you mention Today Tonight.
