My dad had a 5088, said it was the nicest tractor he owned throughout his farming years. He sold it when they (mom and dad) retired from farming and had their auction, and he regretted getting rid of it almost immediately. He kept the JD 4010 (and a Farmall H) because they were smaller and better suited as yard tractors. He got a good price for the 5088, though, so that helped a little, but not enough to ever completely soothe the string of selling it. I wish he’d have kept them all….4 Farmall tractors (a B, H, Super M and Super M-TA), 2 IH tractors (1466 & 5088), 2 IH combines a Case and Case/IH swather, a JD 4010, and an odd ball Steiger….IH plows & disks, straw chopper, sprayer, wagons and several grain trucks (IH and others). The implements I don’t care so much about, ditto on the Steiger. I do still have the H and the 4010, and I bought the McCormick Deering 200H manure spreader at the sale, which I still have. I’d love to have all the Farmall & IH tractors back, shined up and all in a row instead of the shelf full of replicas, shined up and all in a row!
