As they have to check the teeth on the flywheel anyway Mani, if you can afford it now woulod be a good time for a lightened flywheel 
Brilliant news Mani they will need to check the flywheel ring gear for damage else they could knacker the new starter and definitely worth putting a new starter in than second hand if you have the wonga to do it.
Sorry wish I'd seen this yesterday because your not to far from me I dont think and i was only out shopping so would have welcomed the break ;-) Also would deffo have recognised the noise as mine does it every now and again on starting for about a second.

Metal impeller for water pump Mani don't get a plastic one.
JJ
Why is this JJ (or anyone) please? Is it a cavitation problem?
Take your starter off and clean up the bendix that should rectify your problem mate without the need to buy a new one its just the crap and dirt in the bendix which has caused it to stick
Bearing in mind most V6's still have the plastic impeller pump they left the factory with, they can't be that bad as failures are not very common.
But if you're replacing, you might as well go for a metal impeller one.
Age is another consideration though. With all that V6 heat over 10+ years the plastic must be getting brittle now.
Iv never done this. and i dont know what a bendix isjust confused right now
The bendix metal in the starter motor will be stronger than the flywheel metal so simply unbolt the starter from the gearbox 4 bolts I believe then unbolt the wires on the starter flip it over spray lots of wd in the bendix area work it back and forth. Let it drain out and keep repeating until the bendix moves freely and easily and job done mate.
You will also be able to view the flywheel teeth through the gap after you remove the starter. Fingers crossed the flywheel is undamaged but I seriously doubt it mate but it should be good enough to keep you going until your ready to change it over a long weekend
Also for the water pump go for a metal one
