This is the first SC that I have owned. I sell Ford's for a living and know of the 3.8 head gasket problem. I have found a few of the problems on the SC's but not as prevalent as the standard 3.8 V6. I have the Mazda 5 speed manual transmission and I think it could have been a better product. It seems that the T5 out of the Mustang GT would have been a better solution.
