I know several people who took out loans to buy a nice used Ford- just to have to take out ANOTHER loan to replace the engine shortly after. Oiling issues=cam phasers. And a quote from a legit shop to change sparkplugs on the problematic engines starts at $300 but is left open depending on how many break off....or in the case of the late 90s early 2000s engines how many sparkplug holes need their threads replaced by a time cert.
