Just wanted some advice on my future purpose, got a few things to think about, and really need some current FTO owners advice

I just got an acceptance for a uni course change, so now ive got 3-4 years of human movement studies ahead (soo happy). I currently own a 93 180sx, stocko cept new turbo, and I really want to sell it and get a FTO to tinker with for the next few years of my studies.
Now some of the things im wondering about... most of the FTOs I see for sale are like 15 or 16k, 80 or 90,000kms, and id rather buy a car that still has under the 100,000kms mark. Hooowever, ive seen a few FTOs more in my price range around the 11-14k mark with say 120-150,000kms.
Now a lot of people have said to me the kms dont matter, especially if its been kept in good nick.. however over the next few years ill be driving 45 mins or so to uni 4 or 5 days a week, which will rack up a fair few kms, and im quite aware that FTOs depreciate in value leading up to the 180,000kms mark... which im guessing i will get to quickly driving 30-45mins to uni 5 days a week.
So is it worth looking seriously to buy one around the 120,000kms mark or more?
The example im looking at you can see here- http://www.carsales.com.au/please/carsales ... istance=25
and
http://www.carsales.com.au/please/carsales ... istance=25
(which is honestly both are a little out of my range)
The only thing really in my range guranteed at the moment is something like this -
http://www.carsales.com.au/please/carsales ... istance=25 ( but 160,000kms

Im not working at the moment, and when my course starts ill only be able to get something really part time or casual... which sucks but thats the price to pay of uni i guess... im trying to get a trade-in value for my 180 in the next week or 2, dont think it will be much, or with private advertising for that matter, maybe around 10-11grand... for the right buyer maybe - stock 48,000kms auto 180sx.. 12+grand im guessing..
So what do you think? Any advice for a guy lookin for his FTO?

Cheers
