I guess its all opion. The AP1 has lots of problems and Honda knows this and so do lots of other owners. Just ask one of them that has had a problem like me. My head lasted until 30K miles and was maintained, never over rev'd, etc. For you non believers search and watch the forums, there are a LOT of engines that have blown. The number of people losing motors is pretty high compared to say: the EVO's, the Subies, the B18c/b16c's, the mr2s, the supras, the vettes, the 911's. Just my 2 cents.....

Well... conflicting comments...

From all of my research, S2000 is a dam reliable car for what it is capable of.
