good deal???? need to know asap?

I am looking at buying a 89 nissan 240 sx with 228, 000 KM on it, i am having the car checke dover by a mechanic tomorrow........ My alst car was a neon and all it did was break all the time for no reason(i dont abuse my cars or drive them bad, i baby them and change oil every 3 montsh or less depending on km's i put on, as well as always make sure fluids are full and clean.).......so how reliable are these cars and how much longer would the motor be good for would you think????...... thanks alto guys!!:) by the way the price for the car is 3,800 candian

If there is no rust and a manual, it's a good deal, if there's rust and/or it's an automatic, it's not worth more then 1000$ CDN.
