You may want to have it checked out, the head gaskets in the 2003 are known to go out about at 150k miles. I have an 03 as well, just fair warning to you. By the nice looking car. Love the paint.
I know they're weeping oil. I didn't notice any coolant issues yet. I will probably pull the engine this summer and do them anyway.
The price was low enough that I would have bought it even if there was no engine in it.
