If the car has been owned by a person that has a basic understanding of mechanics and knows how NOT to abuse a clutch then you shouldn't have to worry about changing one out well past 50 or 60k.
A well maintained and driven 328 shouldn't need a transmission until then either, probably closer to 100k
It all depends on how the car was used. If it was driven moderately on the street then the above figures would hold true. If the car was tracked, subject to lack of maintenance or just plain beat then you'll see problems much sooner.
Cost? Always much less when you do it yourself, especially if you shop around for parts. From what I have read a clutch can be done for under 700.00 USD, probably less.
Used transmissions can be had for 2500.00 USD and up, if you can find one. I would contact www.trutlands.com for a price on a rebuilt transmission.
