Gym equipment can be good even if old. However, modern equipment works so much better than the old stuff. Who here would use that leg extension-leg curl? I haven't seen one like that for decades. The leg press and hack squat are primitive and probably need new wheels. Most good machines use linear bearings nowadays. If equipment is smooth then that is half the battle. There is no excuse for the extremely bent bar on the Smith machine. They need plenty of racks and more plates.
Benches and squat racks should have safety stops. Upholstery should be replaced when holes are in them both to protect the padding and for health reasons.
Tell the owner to look for used equipment from auctions when gyms close. Even equipment 5 or 10 years old can be cheap to buy. If they replace one piece of equipment every 3 months they will have a much better gym in a couple of years. I see no point in keeping old equipment just because it is old. I have seen a couple of gyms like that in Sydney. I told one owner that he had a museum because the equipment was primitive and from different builders. The comment wasn't appreciated. Of course, I design and build most of our gym equipment and still have trouble keeping up with requests for new and different equipment.
From the photos it seems the owners never reinvested much at all in the premises and equipment.
