people usually say that 20,000 mi. a year is what someone should put on a car... so if they are buying a car and its more than that then they offer less money...
As far as me I live really close to work as well so i only put around 600miles a month... but ill be going to school soon so it will jump up to around 1300-1500 soon

... ohh well what can ya do? (by the way, that figure includes me getting rides to school every other day...)
