I'm new here and i'm sure this is a very interesting community of MKZ lovers. So i have a 2013 MKZ with about 230.000 miles. It has had only one owner and still runs great because all maintenance was done on time. What can I do to regain the confidence of its performance over time? I was considering changing the Engine to something with fewer miles but this is a hybrid Base and I'm not sure what to do, please advise.
