MTA is pretty good used them twice and they are very critical... cause of the smallest bit of rust on a car they were like yeah its got underbody rust... it was literally a dot on the bumper... underneath haha
These guys arent too bad. I just gave them a call and they charge $250.00 (gst included) to check a Mitsubishi FTO. The test goes for 1 & a half hours roughly and they also do a free revs check. Also a 10% discount for people under 25.
