DT408, air brakes, good rubber, and no rust--at $3K I don't think you can go wrong.
As far as speed and climbing ability, it all depends upon the rear gearing. If it has slow speed gears it won't slow down on any hill. If it has high speed gears it will slow down on hills. You need to remember it is only 190 HP. If you want to go fast and not slow down on hills you are going to need in excess of 300 HP.
