Car problem

Last month my brother in law and his family went uphill at Genting Highland. He is driving his old junk, Proton Saga with 4 of them. In fact his car not that old, just old it look old to me. Usually his car never gives him any problem while traveling. However this time they are so bad luck; his car breaks down while driving half way to Genting. His technical knowledge towards car is limited, so he is having problem troubleshoot his car this time. End up; he has to call AAA to tow his car for thorough service. Of course he has to pay quite a sum for the service since they tow from highway to their workshop. Perhaps he could try some parts from midwest auto recycling since many commented the engines from them are very reliable and long lasting.
