hi all! my name is mark and im looking to get an 2002 xterra se (3.3l v6) with 64k miles.i have a couple of question regarding the x. with the vehicle being 11 almost 12 yrs old what do i want to look for in the vehicle for issues or common issues? how are the x's to work on by yourself? how reliable are they? would i be able to pull my boat with the x (i have a 16ft alum basstracker)? thank you
