Recently my dealer has offered me a deal on a new Case/Ih Puma 140. I would be trading a Case/IH MX120. Is this new Puma as reliabile as the MX 120. The cab looks like it is the same as my MXU 100. Have they made improvements from the MXM series,I understand they were a flop. I am a new member to this site, any information on the subject would be appriciated
