How dare you question whether you should buy a new bike? At the magnificent age of 77, you should definitely buy a new one, if for no other reason than to renew your passion for riding (and the accompanying desire to get your money's worth out of your new purchase). You're 77. You deserve a new bike. It's probably going to be your last bike (before buying your first recumbent, e-assisted trike). There really shouldn't be any discussion.
Edit:
Carbon is supposed to dampen the chatter vibrations, but like the other guy said, improvements in the ride begin with the tires. But why quibble? Get yourself a new steel bike, for goodness sake.
