eyeballing a rx8 engine?

So I'm going to meet up with a girl tomorrow who will potentially be selling me her 04 rx8 if everything's in order. When looking at the engine what should I keep my eye out for that would warn me as to the condition of the engine? I don't think she's going to let me pop out the air box and take look at the coils and whatnot so what all should I look for that would indicate the engine status? By the way I'm not purchasing it tomorrow, simply looking at it and Saturday I'm probably going to take it for a compression test before purchase but I don't want to waste the money on a test if I can see something obviously wrong with it just by looking at it.



Thanks
