My brother is looking at 1999 KIA Sephia on craigslist, the owner says that the radiator, head gasket, and timing belt were replaced. The vehicle has 115K and a beautiful body. My questions is, I have had three sephias before and I have never had either a radiator or head gasket issue with any of them, his current one has about 150K on it and the only issue is rust, its rotten and needs to be replaced. Can anybody tell me if head gasket and radiator problems at this low of mileage is as alarming as I feel it is? This makes me wonder if he is dumping it for other reasons. Any feedback/advice is very much appreciated.
