it is steep - £30 odd quids worth of parts and maybe 2 hrs time maximum
change a fan belt, clean the muck off an ABS sensor and replace a sensor
I dont know your job, but what do people get charged for your time, and if you supply parts do you give them at cost?
And any mechanic will know its not just "change a fan belt, clean the muck off an ABS sensor and replace a sensor"
I take it youve never done one of these belts?
Im saying for me it would have been cheaper to do it myself, and Im quite confident that 95% of commercial garages do a sh*t job, because theyre staffed with fitters and technicians nowadays.
Im not sure what engine he has but Ive replaced belts in quite a few vectras and cavaliers.
The faulty sensor was probably just dirty - they usually are - and a cam position sensor is normally quite handy changed.
