considering 93 Century- 6cyl engine questions

I have found a '93 Century with the 6 cyl. engine with 49k miles on it. Everything feels strong on it and I'm considering buying it to get me through a tight financial crunch until I can buy something better.

What would the engine need wrt maintenance at this point? Is this an interference engine? Does it need a timing belt or is it a chain. If a belt, at what mileage/age would it need replacing?

Thanks for any advice on this purchase.

The 3.3L V6 uses a timing chain.
