Indigo GT I have used and I am very happy with them. I have used them before myself and friends as they work with Evo's and many Japanese Performance Cars. However they have recently become Revo Dealers so I highly suggest using them.
I would say Gotboost m8. why don't you pop down with us all on the 11th..
We are doing a rolling road day, you could have a chat with the guys down there.
And see wot they can do for, and chat to the other guys.
