Advice for purchasing a C30?

[a73s]

Hi,
I own an XC 70 for family driving, but I am in the market to buy a (used) replacement for my VW GTI to have a smaller car. I've been thinking about the C30, maybe a 2010-2013 model because I love how it looks, but before I dive in I have a few questions.
I'm concerned that since it's no longer made I might have trouble finding parts?
How much life is left in a C30 with 80k or 100k miles on it..?
Any lastly, are there any things to look out for, or known potential problems?

Thanks for any input, I appreciate it!
Alan.
