 Bought a CPO 06 20k mile VW passat that is a piece of crap & literally had everything replaced within 6 months - a few of them within 3 DAYS of purchasing the car. From entire AC system to radio to ignition module to steering column, instrument cluster to heater, gas tank dropped & replaced, fuel injectors I believe, coil packs, fuel lines, radiator leaking, water pump, driver door handle because it stopped working & had to crawl in passenger side!! Driver door striker as well on a different occasion, almost all suspension parts, rear struts, the list goes on and on.... Those are just off the top of my head but almost every moving engine part, suspension, & electrical item was replaced, yet
