As was previously stated, don't be afraid of a prior lease, maybe even lean towards one because people often try to keep them extra clean so it doesn't cost them any extra $$ when they turn it in. Mine was a prior lease from a state that doesnt use as much road salt as Michigan and it was clean as a whistle.
If the vehicle was ever used for serious offroading it will probably be obvious under the vehicle somewhere. Check the skid plates and rear shock mounts for any evidence of impacts or scratches/gouges. If the vehicle was used for "mudding" or other romps through wet fields you will probably find some mud up under the vehicle in the cracks and crevices. Mud gets everywhere and it can be difficult to all of it off so while you're looking at the skid plates, look for any mud caked under the vehicle.
Good Luck

 

Thank you, your right, I shouldn't worry about lease ones so much, thanks also pointing it out about scratches at the buttum and mud signs, that's what I need to check, also as mentioned earlier I should start test driving every h3 I see to get a feel of it so ones I. Choose one I get have an idea of it's driving quality.
