Just found a listing for a chap selling a 2010 Mini Fastrak w/ the honda engine...only 9 hours on it. Asking $3500. Is this a reasonable price? Also, I would use this mower on my 1/2 acre lot and may use to mow the lawn on a few of my rentals and office as/if needed during times of vacancy. Basically mostly residential w/ some periodic commercial applications when needed. Would this unit be able to handle the workload? Seems about the same price as a new sport so not sure which is a better way to go if the $3500 price for the used mini Fastrak is fair.
