Non-vented battery? Shame on you....
IMHO, if you want to get anything over $4Kish I would clean the interior (especially the air bag and center arm rest). The smudges show up very well in the pictures. Give the interior very detailed detail, leather cleaner and conditioner included. Also, replace that cap that goes on the a/c high side.
Even with all that you're still over 100K miles. Most people look at 100K as the end of a cars useful life. Not so these days, but it is the perception. My 2000 V6 has just over 160K miles and I just now have to do the 2 O2 sensors (the sensors after the converters are monitors and rarely fail).
Here's an idea. Sell both and get an '06 for you!! They run in the ~$17K range with lower (<50K) miles.
