Is the number of indexed pages of an aged domain important ?

[Lafaso870]

I want to buy an aged domain that will expire in one week, it's has exactly the same keyword(.com) i am targeting. 0 PR, Age: 3 Years, 26 Backlinks and 1900 Indexed pages on google that had a good content related to the niche. So is it good a thing to have those indexed page or no ? will they add power to my future website ?
Thanks.

I suppose that it can be profitable to have indexed page on Google. it will generate traffic to your web sites.
