Looking at buying an S60R
 

Hey all - first post here, I grew up working on cars but I'm a Volvo noob.

I am looking at a 2004 S60R, auto. You can see the ad here:
2004 Volvo S60R

I'll be looking at it later this week. What should I be on the lookout for? How do head gaskets hold up on these? etc etc

Thanks
