Maintance- S13 Style $$$ to MaintaiN>>?

[240SX2S15]

Hey Im stuck on deciding what type of car I should get. I love the 300Z but the 240SX there is something about them. I like the older style S13 and the newer ones. But I was wondering as the years past does it take a lot of money and time to maintain a 240SX. I mean like expensive stuff like tranny and checkups. I'm looking at this black S13 with gray cloth with 78K for 3200. I mean it is nice but Im still stuck on the drifting look I mean drifting scope of things. Also wheres a good place to order all these parts because do they start to break down at like 100K or what. Thanks for your help.
