Rusty exhaust resonator - when will it die?

jpg90

All,

I'm considering buying a 2006 Volvo XC90. Among other things, I noticed what appears to be a very rusty resonator of the exhaust system.

I took a few pictures of the resonator, along with another one of the exhaust towards the muffler, which I've posted further below.


I live in Southeastern PA - near Pottstown. So we get plenty of snow, rain, sleet, slush, and salt. The car will NOT be garage kept. It will be driven about 10k - 15k miles per year.


Questions:

1. Can any of you please tell me how long do you think it will last before it needs to be replaced?
   
2. Also, how could I get a good estimate of what the repair bill would be like?
   

Thanks for your opinion.

Best,
