Run!

There are tons of Boxsters for sale, save some $$ and buy one that's worth keeping. If you had to replace the top, you'd be in for over half of what you paid for the car, not to mention whatever else will bite you in the @$$ on an 18 year old car with well over 200,000 on the clock.
That is unless all you want to do is drive it until it needs repairs and then dump it, but hey, that's up to you. Best of luck whatever you choose.
