240 overheat?

[cys19]

I went to see a '95 base model 240 today with a mechanic and we didn't buy it b/c he said it wasn't a good deal. He's not very English proficient, but he said something about the head gasket and the radiator causing the water to overheat and something about salt (?) and something about the water under the valves (?) and that it would be extremely expensive to fix. What do yal think?

Edit: Also after we left it running for about 5 minutes after taking a test drive, the engine quiet down and he said something about the oil not being able to get into the motor or something.

The guy's asking for 4k and the car has a replace motor.
