 I brought a 1998 5.4L Eddie with 102,000 miles in Nov 2004. It's now Jan 2013 with 190,00 and this dam thing runs like its on steriods. Just got back from a 1,000 mile round trip with ease. Only problem in 9 years of ownership was an altenator replaced because I helped try to start someone's bmw and it damaged the unit. I look forward to another 75,000 miles (knock on wood) before I even consider sending it to the local car sales lot for retirement.
