I've owned a 2007 FX45 since new, currently 112k miles. I've replaced front wheel bearing (when she was younger), and...that's it for actual problems. I perform nearly all of my own maintenance. I change transmission, differential, and coolant fluids at 50k mile intervals, just replaced the spark plugs at 108k miles. Recharged the AC once. Oh, almost forgot, the navigation DVD-ROM (under the front passenger seat) started to fail just after 90k miles. At about 105k miles, I replaced it with a unit pulled from a wrecked Armada. I regularly send engine oil samples to Blackstone Labs for analysis. Nothing alarming found, some lower end bearing metals, I fixed that with 0W-40 oil. If the maintenance records check out, I'd feel fine with a $9k price.
