Took my 2004 4Runner to them for a P0020 code. Code is for an O2 sensor and that means it could be the sensor or something else further down the electronics/computer rabbit hole. The more expensive rabbit hole. RM could have up-charged me at every turn. Not only did they NOT do that but they went above and beyond by fixing the shoddy radiator install from a different shop. There’s a reason their score has maintained. Highly recommend.
