Go For it!
Looks like a decent sled. The very first thing I look at is the bolts on the scissors and the suspension. If they are too rusty then you know the sled wasn't stored in a dry place. Original skis too. The rear suspension is also an upgrade on that sled. That is not the original suspension, so +++. Someone on this site will tell you what the suspension is, maybe an M10. I do not know much about the different suspensions. Below is a picture of a stock suspension.
If it runs well. I'd say it would be a good deal.
The Bronco looks pretty decent too, other than the couple rust spots.
