Let me clarify. I bought my car from Peter Davey in Werribee. My first 1,000kms inspection/check-up was with them, they fixed my A/C (under-bonnet) rattle successfully. Great service. Werribee is however very inconvenient for me, I only bought my car from there because they offered the best deal. The idea was I only go there to pick up my car (test-drove elsewhere), and that was to be the only trip to Werribee. The 15,000 service was done at another dealer. That's where I had to take my car back a few times for poorly completed dash re-assembly after they attempted to fix my dash rattle. It is this repairer that I was unhappy with. I'm reluctant to name them just yet in case it was just my car and I that was unfortunate... Let's just say that they're much closer to Melb CBD than Werribee is. To answer your question (what should you do), if Werribee is convenient for you, lucky you. Stick with it, I would. Theres an old topic/posts regarding dash rattles somewhere on the forum as I had my car in about 4 times before they decided to get a new dash from Japan. this still didn't fix the problem and so Toyota Tech in Melbourne got them to check the wiper assembly under the cover in the engine side/firewall area. sure enough there was a cover under there that had hand tigntened nuts and the cover wad rattling away and coming through like a sort of dash creaking noise. even though its now fixed, my car has never been the same as there is small scratches and nicks and grubby marks from having the dash pulled apart so many times. just be careful that you don't end up with the same problem. good Luck!
