So I found a 2005 element in my price range, one owner and well maintained...but it has around 168,000 miles and has some rust on the back lower tailgate under the plastic panel where the license plate bolts on. Is this normal? I'm so hesitant to purchase it now, but I got the owner down to almost $1000 under book value, so I feel like it's a dumb to miss out on it for a bit of rust and higher miles. What would you guys suggest? Thanks!
