First Car - Have I been ripped off??

Water pump is common to change when doing the cam belt as the belt often drives the pump and the bearings tend to go when the pressure is released after a long time.
Coolant should have been changed but can be very dirty very quickly if they didn't flush the system and unless you ask for this it's unlikely they would do it. Get an antifreeze tester from halfords as that will give you an indication as to whether it needs changing.

Glow plugs only ever come out when faulty. Never changed at service time.they are not like spark plugs that need adjusting, they are just heaters.

I did wonder if it could have got dirty from an old unflushed radiator or something, but it looks old...like old like my Fazers coolant that had never been changed for years. My Fazers coolant is still orange now after 2 years, granted I did fully flush the system. Is it possible it could have really gotten dirty that fast? How much would an antifreeze tester be do you reckon? I thought glow plugs were possibly not a serviceable item, no worries I'll get them changed anyway.
