How many miles is too many miles for a newer Honda?

I want a Honda Civic. I found a black 2008 model that I like, its around 11K$, great condition, but it has 108K miles on it. I know these cars go forever, but how many miles is too many miles to buy a Honda with? I'm buying it as my main car mainly to save on gas, but it will be my only transportation so I need it to last.
