There are less and less 535IS's available but I would have to agree that unless you are prepared to do the body work it is not worth $3500. If you can get it for $1800-1500 then do it. Use the money you save for body repair. I own a 87 535IS and I would recommend checking compession, shock towers, brakes and exhaust. Also, see what tires/wheels have replaced the original metrics. Hope this helps.
