Going to go off of the things that are highlighted, barely.
Pricing seems fair, but was the quantity explained? I mean looking at the brakes, you only have 4 wheels right? So I'd assume only times 4 not 6.
Aem Wideband O2 is a fair pricing considering install and making sure it works.
Don't know about the power steering pump.
And the rewiring I'd inquire about why the quantity. Pricing seems as if he would be replacing the wiring totally not just cleaning up.
