IIRC, the P-85 was Ruger's first centerfire auto. They had some bugs which were pretty much worked out by the P-85 Mk.II and certainly by the P-89. By the time the P-90 came out, they had a very reliable and accurate pistol.
They're just big and clunky by today's standards and if I had one, I probably wouldn't sell it low enough to get rid of it. Conversely, buyers can get all sorts of newer designs in the $300 range, especially if you go used. There's nothing wrong with one as far as functionality or accuracy and even beauty is in the eye of the beholder. Lots of people didn't like their looks from the get-go. There's not much difference between them and the P-85 or anything in between. Lots of people don't like the look of a Glock either though.
I've owned all models mentioned and never had any problems with any of them.
