Not yet. They will keep driving it and will replace it with a newer X3, it'll be their third one.
Leaning towards taking it, not having the catastrophic chain guide makes a massive difference.
Tempted to get it, sell it and my Highlander, and get into a newer Highlander. But like I mentioned earlier, my wife really likes the X3 so that's going to be a factor.
The only downside, is that my '07 HL is pretty sorted, drives great, and the rust is being kept at bay thanks to regular rust-proofing and washes.
