[sarekire9]

so i have this friend who wants a jeep and i have an old cherokee just sitting in my garage..it has 170k miles on it but is in good condition and i want to loan it out to him..as long as he keeps paying he can pretty much have it ya know?.. i cant think of a reasonable price to give per month
