Help me find my first

How much has it changed from looking at the photo he posted?

It looks identical on the outside, besides the wheels.

Update: The last registered owner's brother saw the ad on CL and called me. His bother has since sold it to another, about a yr ago, either in another state or they haven't registered it, because new owner doesn't show on my Oregon DMV records. He is suppose to get me the info of who he sold it to. Still anxiously waiting for the call back. Good news is that he had zero problems with it, and took great care of it before it sold. Hopefully the current owner is the same.
