Should I buy it?

[sb3]

I'm currently looking at a 1999 996 C4 with 100k miles. Looks to be in decent shape and has most of its records. Has had regular maintenance and the clutch replaced. The current owner does not know if the IMS bearing has been replaced or not. Its a relatively cheap car at ~15K and my plan is to drive it as a 2nd car for awhile and possible turn it into a track day car eventually. I'm sure I'll have to with replace the IMS or motor at some point. I'd like to hear others thoughts on this plan.
