Mine 2008 bought in March 2013 with 1500 miles. I put 6500 miles on it so far in 1/2 years, so around 8000 miles.
FYI: You won't find very high mileage G/V's here (if that's what you are looking for). Also, in the US we drive only "relative" short distances with them as a secondary vehicle, in Europe it is often main transportation, such G/Vs over 75,000 miles without engine rebuild are quite common.
PS: I had one with 14,000 miles when I sold it and the previous owner must have abused it (probably ran it once on very low on oil level or bad oil) and it used a 1/2 quart/liter between oil changes; the one I have now with 8000 miles on the Odometer uses not one drop of oil between oil changes, and still nice clean after 3000 miles. So, preventive maintenance is everything relating to how long the G/V will last.
