Im about to buy a 720 and im super stoked, im gettin it for 1.5k with 140k miles on it (i have no idea if thats a good price or nah) the windshield is cracked and the owner said the control module for the AC is out, is that an easy fix? Im also wanting to eventually mod it out by either trying to get it more power, or lifting/lowering it or converting it to 4x4 or something along those lines. any tips on some good mods for it?
