the usefulness of any advice can be judged as very useful by the giver and perhaps not so useful by the reciever, especially when the operating system of the vehicle might be totally different than the older model.
and of course a former owner who really thought so much of the vehicle would never dream of publicly and privately disowning the vehicle, sure they may have constantly droned on about how well it performed in their day, as opposed to in their opinion, the poor performing current model, but they would never have disowned the vehicle.
a bit like me and the ife really. i have and will always support the ife, i might have issues with bits of it, but i believe that those who steer its course do so with the best intentions and i wouldnt ever dream of publicly disowning it.
