Vokera excell 80sp, it's no country for old boilers.... repair or replace.

Hi Guys/gals, i know the subject of repair or replace old boilers is a very divisive matter.
Some engineers will always repair and others will advise to replace.

I have to attend a Vokera 80sp on Wednesday to diagnose a problem with intermittent hot water.
i have a few preconceived ideas of what it might be, but only eyes and hands on will give a definitive answer.
Customer has already intimated that the boiler is very old and may need replacing. They would also like to know if it is worth repairing.
My thought is if it's a simple repair i would say i can do it but still steal them towards having a new boiler installed.
How do you guys and gals approach these matters?
is there a process or age limit of boiler that you use as to which way you lean.

just being inquisitive.

I can repair but no warranty. By no warranty I mean absolute none what so ever.
This is price to repair and this is the price to replace, your call.

PS I don`t do boilers by the way just water pumps.
