Thanks to you both. I have no idea why it is plated at 3.7 or who did it. It may be that is was manufactured at that weight.
The only reason I was considering the change is because I am selling it and I feel it may be putting buyers off, especially the more mature buyers (like myself).
If I don't sell, then in a couple of years I will have to do the necessary for me to continue to drive it. (Reaching 70)
