For two-up touring, you might want to consider an aftermarket seat. Possibly a different windscreen as well.
Where are you located? Any photos of the bike?
Very reliable bikes. I sold my 2007 with 295,000 km and no serious problems. Nothing done (ever) to engine, transmission, clutch, cooling system, or brakes and it never burned a measurable quantity of oil between changes. Regular maintenance only, other than a couple of minor (mostly electrical) issues early on for the '07. Gen III bikes did not have grounding faults like the early Gen II bikes (esp. '06 to '08).
160,000 km so far on my 2011 but without the electrical issues.
Valve checks, brake pads, fluids, lube, sparkplugs, air filters, couple of sets of fork seals/bushings, one battery in each bike... Oh, and one set of front wheel bearings and one gear selector switch. Maintenance is easy - without dealer intervention if you have modest mechanical skills. Lots of experience and assistance available on the forum.
Edit: Aftermarket suspension (especially rear shock) is worth considering, especially for 2-up.
