I have a 2006 Lexus GX470, little brother to your LX470. Like Richard said very comfortable and quiet and awesome off-road. Easy to tow, put transaxle in neutral, leave key on to keep steering wheel unlocked and tow away.
Make sure your timing belt has been changed, usually needed every 80,000 miles, change water pump also when doing it. Other than that it's a great engine. My mechanic has a 4.7 in a Toyota truck and has well over half a million miles. Mine has the airbag delete and a 2" lift.
I added a toad charger to connect 12vdc from my coach to the GX470 to keep battery charged while towing. Having to leave the key on caused a drain on the toad battery. I also had an unchipped key cut to leave in the ignition while towing.
