Its at penrith plaza. You can go there any time, the guards don't usually care. In fact they usually come up and say hi. One guard came up last night and was talking cars to me, and recommended deviantart.
I took the pic there with only half the car reflected because I thought it was add something interesting to the pic, but in hindsight I might have tried to get the whole car reflected. I'll do it that way next time and compare.
