Getting a 1ga gsx w/ evoIII engine - What to look for?

[eagle talon guy]

I might be getting a 1990 eclipse gsx with an evoIII engine in it.. What are some things I should look out for? It's a 5spd, about 150k on it, has a sun roof..

Anything you could warn me about, or anything that is infamous about these?

I have a 1gb, but I'm assuming since this one is older, there is prone to be more things that go wrong with them...?

Let me know!
Thanks.
