Looks like some of my points have been taken out of context...
Fair enough that I made the mistake on the 3.0L water pump.
I assumed, wrongly in this case that like the other Busso's it would need to have the upgraded metal based pump, which its already got.
The OP only mentions that on the last service, that this had not been done. He has not mentioned any earlier history / work done. Therefore, you have to make a few general assumptions at this point, based on the information given.
The point I was making was that he is looking to spend in excess of £4K on a car that is over 10yrs old.
Therefore, in my view (whether you agree or not, we'll beg to differ as it were
) ...If I was spending this kind of money on a 10+ year old car, where a fairly critical component had not been replaced (assumed, ever!), or there was no obvious history of earlier replacement, then I would have some concerns.
I would not hope for the best as you put it, in that you could deal with it on the next service.... as it may not get to the next service.
This depends upon your attitude to risk vs. cost.
If the GTV was say £1,500... then sure, maybe you would go a year/or 2 and then have it done. If it went bang, you could spend out around £800 for a replacement engine, bits, labour ... maybe a bit more and you'd have spent £2,500'ish.
However, £4,000.00 in GBP or Euro's is a big chunk of coin fella's.
I did not say to the OP, do not buy it.
negotiate a very good discount at this kind of money, or (as he appears to be unsure) go and find something else. There is afterall choice and if the car doesn't feel 100% for you, then shop around first.
So, to put it back in context... your comments would be appropriate on a sub-£2K outlay. The seller offering his GTV for £4K++, should have and this is purely IMO, replaced the water pump. Especially if its never been done and its 11 years old.
It's also an indication to me, what else may have the seller not done on this service, i.e. Idlers, Gaskets??
I dunno, the OP information was basic.
I was only making the comment based upon my impeccably maintained V6.
Everything was replaced at 65K and Everything was replaced again at 119K...
but that's my choice to spend as I see fit. I usually take the view of "well if its all coming out anyway" I'll buy that part and have it put in. **Preventative Maintenance Replacement** is always cheaper than Reactive, IMO
Very similar to any engine out work... good idea to maybe change the clutch, as you'll only pay for that part whilst its all in bits. Subject to mileage etc and any other variable of consideration.
