Went here for an oil change for my 2011 rav4 that I bought from them in 2012, and was told that the rear brake pads were down to 3mm, which is dangerous, and they also offered to change my air filter for $49 which just cost $7, and takes about 1min to change, I said maybe next time, then when I got home I checked the rear brake pads myself and they were 12mm, so I didn't like the fact that they charge way to much, but then they lie to you about needing work done that you don't need, that's the true meaning of ripping people off.
