I didn't realize door locks were a option on the 80 series. But checking the Ebay auctions it seems 4WD was also a option.
So what is the 80 worth? It does have only 51K miles but who is going to spent that much on a 80 and then wheel it, plus no locker. In 97 you would be better to find a low 40th or even better a collectors edition for kind of money.
A couple 80's with low miles recently sold for ~$20K but they were locked. My guess would be 15k-17k. It is the correct color, white
