Given enough time behind the wheel, most drivers will be able to keep their coach between the lines, no matter how bad the set up is. That is a given.
We have all driven a new vehicle and naturally it feels different. A self diagnosis that said "feels like I was over steering" may be factual, OR it may mean there is some slop in the steering box, idler arm, or tie rod ends. Which one it is depends on a complete inspection of an 11 year old vehicle with an unknown history.
ALL empty coaches will handle different than a fully loaded coach. The only right answer to this perspective buyer is to have a complete inspection of all aspects of the suspension, steering, alignment, loading, etc. Then, and only then, will he be able to get a true experience of how THIS vehicle handles.
