First Car Possibility

[New-B]

So Im looking into buying a ti from my grandfather, the whole thing to me seems like a no brainer to me but i would like some advice from owners. The car has been maintained extremely well and has and one owner (my grandfather). Not positive but I believe its a 96 with around 100 to 120 thousand miles on it. I could get the car pretty inexpensively and thats why it seems like a good idea to me. So here are my questions:

- The clutch pedal on the car is loose, is this a minor problem?
- Would a 6 cilinder engine swap be worth it? (Im aware of all it initials)
- I've never worked on cars before, is this a good place to start?
- What are some other good performance mods for these cars?
- is it a good first car for a 17 year old kid?

Thanks
