Normal wear/tear is brakes, clutch, wiper blades...etc
Cam Phaser is a motor failure IMO
Btw, after you get it, change the oil with Motorcraft FL-820s filter, and I highly highly suggest only using 5w20 per Owners Manual
The 5.4 3v is particular about her oil. 5w20 is good enough for 500+ RWHP motors, and served me great with my Supercharged 5.4 3v
