Still running my 2008 Fit Sport at 204k+ miles, and the ride seems fine. Is there a mileage that you really should change the shocks? Not running it hard, back and forth to work, off day running around. Been to Texas and back. El Paso, even. what do you think?

 

Replacing them would certainly benefit the ride, handling and braking of the car. If it all performs to your satisfaction and they are not leaking then no need to change IMO.
