I have a 98 Navigator, bought new in 98. Currently at 495,182 miles. Original engine and transmission. Expect to hit 500,000 by March. Wife drives 2004 LS, with about 250,000 miles. Prior to Navigator had a Continental which had reached 369,000 when I gave away. Just wanted to post this because Lincoln vehicles have been good for me and wanted to give credit where credit due.
