Potential buyer of my vehicle did a prepurchase inspection here. 1.Said LR door didnt work, walked over opened door, worked... 2. Said battery system was showing approx 13V while running (suggesting alternator on way out), and when turned off, battery dropping rapidly to approx 11V, and said new batt $600 for special sealed AGM battery - test at home myself, 14.7V while running, dropping 13-12.8V when turn off over approx 1hr, 12.5V 20hrs later (considered a healthy "resting" voltage after the surface charge has dissipated). New batt specifically for that vehicle via Repco or Supercheap $180-280... One or 2 valid points to be expected, but with these misses, and the excessive repair estimate, I'm pleased buyer was with me to test and check some components when I got home. Definitely wouldn't go there unless I was buying a car and needed a prepurchase lol.
