I'm looking to buy a little runaround and I've been to look at a 1998 Megan 1.4e with 100,000 on it. The previous owner is selling it because he's been given a company car/van and they have a family car already. He's replaced various bits and bobs like driveshafts, springs, ball joints, cat, etc. and the car is in very good condition. My only worry is that the heater is blowing cold or to be more precise luke warm. The engine temp seems to be ok i.e. starts off cold then rises to about half way up the guage. I suspect that the heater matrix is duff but I've also heard they have a habbit of head gasket failure. Does anyone have any experience of these cars and the possible causes and cures for a luke warm heater.
