Advice on car im about to buy needed!

[Uzelac]

The subject is covered million times.
There is buying guide on aeu86 also, other can be found on many other AE86 enthusiasts forums/blogs.

Long story short: if the car was taken care of, and body/chassis is good (no or small rust) 150k miles is nothing for 4AGE and AE86.
But... little rust is kind of impossible for northern hemisphere and cold/wet climate, and it's hard to be sure someone has taken good care of a car that's 25 years old.

Even shorter: take a good look at it.
