That sounds like the local Toyota stealer. Took the wife's Toyo in for a 30K oil change. They came up with a fancy spread sheet that only had a price tag on it for $450. The guy even kept a straight face when he presented it. Toyo does not call for any of that stuff. :R
The sad part is that I have been setting in the waiting room when the service guy comes in and recommends crapola like that and the silver haired senior citizen says something like, well if it is necessary, I guess it needs to be done.
