DO NOT TAKE YOUR CAR TO ROTOMOTION.
I have taken my skyline there and had nothing but trouble.
Rotomotion will do things like:
You take your car there to ask them to run it on the dyno, check your afr's and see what it's making power wise. Should take 15 minutes. They'll keep it for a week, when it was booked in for a single day, then when you pick it up you'll get a stupid excuse like "Oh, there was a car/box/feather in the way". Seriously, I know there's a rotomotions account on here, if there is a car in the way of your dyno, how about just just move it?
You take your car to do a fuel pump, they quote you x amount, when you pick it up (again several days after they had told you it'd be done) it's double that. A year later you go to a real workshop and they tell you that you need to redo all of their work because the wiring is dodgey.
You take your car for a clutch job, they take much longer than expected, charge you much more than they quoted, and then after a week it all comes apart because they haven't installed it properly.
DO NOT TAKE YOUR CAR TO ROTOMOTION.
Seriously, shits me that people still talk about going there as if it's the best place in the world. I've heard nothing but bad things about them and had several bad experiences myself.
