Here's a want that can be more easily acquired. It's a model version of John Deere's Gator RSX 850i, made by Ertl.
It's pretty neat, a normal proportion side-by-side, as opposed to the typical Monster Treads Gators intended for kids.
The reason that this is likely more easy to get is because I could probably just go to the nearest John Deere dealer and buy one.
