Colin, the 60,000 mi. service will probably cost over $1k if done at a dealer. You are also looking at about $1100 for Bilstein HD shocks/struts- don't even think about stock replacements. About $350 for springs if you want to lower and/or stiffen the car a bit.
About $500-$1000 to install , align and corner balance. You would probably also want to go with larger sway bars while you're at it. about $400.
Rotors, pads, sensors, spiders will cost about $700.
As for the original question- value.
Considering your description of the interior and exterior as being 'perfect' - I would say about $30k. $2k either way- depending how quickly he wants to sell it, or how bad someone wants to buy it
good luck,
