If it's on a dealer lot, request the carfax, head issue should show up if it was done by a dealer under warranty. Other than that, an 06 Adventure is a great H3 but lower the $$ some. 63k is nice and low.

 

That's a great point, get the carfax, the head could have been repaired. I would still offer lower, because of the fact that there is an issue with the three-five.
Low mileage is a key to value, however that engine doesn't carry the value ($9k when you get to 100k right now).

 

If it has over 80k miles I wouldn't worry about the head. It was probably replaced already if it was going to go bad.

 

sounds like a fair price, I would recommend checking the U joints as well
