you can find plenty of horror stories about head gasket/cylinder head bolt issues, I haven't experienced that at all on my 03 with 110,000 miles. Other problems? Sure, but that's why most of us are here, to get help from others with more experience. If you're a dedicated gear head, buy the car you like in the best condition possible. Keep in mind, you will be looking at a car that originally cost $50K or so, so you'll be buying parts and service for a car of $50K, not the used car price you're paying.
