Oh it gets better, Last year I took my GTS to the dealer for an oil change and they put a TRD filter on.
Yesterday when I went in to the parts dept of the same dealer they had no idea what the right the part number was, so I ask them how they knew which filter to put on my car the last time I was in, they could'nt give me an answer, they just gave me the part number they used the last time (00602-90915-006)
I'm sick of Toyota treating the Celica like a red headed step child
