Service advisory items & likely costs

[Griffit]

A car I am looking at had the following items listed when last serviced but I don't speak enough Porsche to translate them all and would be interested in ballpark costs for rectifying if anyone has them?

Coolant leak for NS radiator - AC condensers were replaced a while before but assuming both rads need replacing what is the likely damage?

Heater matrix membrane unbonded? I know nothing about this - is this a five minute job with a tube of sealant or a matrix out fit new gasket type fix costing a fortune?

I think rear discs & pads are necessary - Rough cost as bargaining point?

Rear brake pipes from calipers starting to corrode - assume these are short sections and inexpensive?

Both front strut collars corroding at the top - not what these are otherwise known as?

Power steering return pipe split to second crimp - part is cheap and hopefully not much labour to fit (+ fluid)?

All four lower wishbone inner and centre bushes starting to delaminate - doesn't say failed but sounds expensive to rectify?!

Any help appreciated.

That would have helped - 996 C4S

SH is all OPC, which I would possibly keep up but indy most likely for other works.

Last service was 15 months ago but will go to an OPC pre-purchase for a Minor Service. Of below:

Coolant leak for NS radiator - A smell of coolant noted 2011, nothing 2013, noted a small leak 2015.

Heater matrix membrane unbounded - First noted as coming away 2010, nothing 2011, noted as lifting 2013, noted as unbonded 2015

I think rear discs & pads are necessary - slight corrosion reported 2010 & 2011, 1mm remaining 2013, 0.5mm remaining 2015.

Rear brake pipes from calipers starting to corrode - first noted 2015

Both front strut collars corroding at the top - first noted 2015
