I have a 1984 Landau Magnum TR (Very similar to a Bass Tracker of that era). I would say that the quality of the boat was good compared to other boats of it's day, but mine was in very rough shape so I needed to do a lot of work. There is a thread around somewhere. I also didn't find much of anything on the internet about them when I was contemplating it. Landau only makes "luxury pontoon boats" these days.
Here's how I see your possibilities:
1: The hull and trailer is good, the electronics are relatively new and of good quality, and working, the deal is good (at least compared to prices in my area).
2: The hull and trailer is good, but electronics are old and you wont be happy with them for long if even working. Electronics start around 100 and only go up. Used could save you some money. Deal is still decent.
3: The hull and or trailer is not good, still could be a good deal if you can do any and all work to repair. If you can't, I would walk and just buy new.
If electronics are old, don't let the seller try to use it to price it higher. Small things add up quick, new batt for electronics, trailer needs rewired, new winch, and on, and on, and on........
Alumacraft 14ft jon $740
Jon boat trailer $500
Lowrance hook 3 $100
battery $100
cheap seats $40
Misc wiring, etc $20
That's the retail cost to buy new, what he is selling used.
