I'm a car repair business owner specializing in Euro Cars. Over the last 18 months I purchased 4 (that is four) used engines from LKQ of which 2 were purchased with warranty. three of these engines failed: 1 within 2 weeks, 1 started up with severe knocking noises from the bearings, 1 did not even start up. I have yet to collect money or be reimbursed for my time. I have been waiting since January 3rd 2017 to be reimbursed for the latest such issue!! Being passed from one rep to the other, one email to the next, nobody in that s**t-place wants to assume responsibility> The latest person to make promises ("I will see this through to the end until you are taken care off') was a person by name Mike Harvey, before that Lori Ann Anderson, JR and his supervisor in Tampa, Frank in Crystal River (FL) and a few others.
Buy your used items at a different company if you have the option! There is at least one other one that I know off that offers a warranty
