I purchased a 1999 Lincoln Navigator with 50,000 miles in January 2003. May 2012 I replaced the battery for the third time. The guy at the store asked me how much work I had put into the car. 3 batteries, 4 sets of tires, brakes several times and a few maintenance items over the years probably less than $5,000. It has been an amazinag vehicle. Gas is a bit costly but now at 280,000 miles I now get 14 miles a gal. No leaks or issues AMAZING. I am a Realtor and this has been the perfect vehicle.
