The ad says it has a Duratec. Alternatively though, that doesn't look like a 2002 Duratec when you see the underhood picture.
I think it's a Vulcan motor. From what I remember, Duratecs were optional on SES and standard on SEL, but I don't think they were available on the SE. I could be wrong though, they could've been optional on the SE too.
