I can't tell you who to go to, but i can tell you NOT to go to Auto Perfection.
I unfortunately bought into the last SAU SA group buy, for two cars, the front windows of the stagea and full tint for my Chaser. Both times I was told to get there in the morning before about 10 and car would be ready by around lunch. Both times I did not get the car back until 5 or 5:30 then was palmed off some bullshit excuse that differed wildly from what I was first told, or told again when I called to see how the car was going.
The second time my wife and I spent the majority of the afternoon (4hrs+), sitting in the waiting area, listening to the pig of an owner verbally abuse his receptionist repeatedly, then whenever an angry customer arrived (we counted 5 in the time that we were there, out of about 7 customers total), he would scurry out the back, telling his receptionist that "he wasn't there", to leave her to take the beating. One poor woman who was also waiting on tint and had dropped her car off at around noon, came back just before we were leaving, to see that her car hadn't even made it into the workshop yet.
What's more, I now have a 3-4 inch long scratch on my driver's side window, pin-prick holes on the passenger side tint and the tint looks like it hasn't bonded to the rear windscreen properly. But i absolutely REFUSE to take it anywhere near them and will have nothing to do with them further.
This is my personal experience. Not my friend's friend's friend's (although I have heard those as well). If I had my time again, I would have paid the $30 or so that I saved in the group buy and gone to somewhere like instant windscreens, where they're nice, they do their job in the timeframe they specify ad you get quality work.
