Welcome in Bruce.

When you ask about reliability, remember that you are asking about an engine & drivetrain parts that are in all Troopers & Rodeo's/Honda Passports.
I believe insuring that regular oil changes & scheduled maintenance was done is your best insurance on buying a used one.
I have 86,000 on mine with no problems other than normal maintenance. I went to Royal Purple oil at 50,000 and the oil is noticably cleaner which I believe is important in this engine.

The recuring thread with most forum members (a very diverse bunch!) is that this is the most fun vehicle they have owned.

Go ahead, Jump in, the waters fine!
