Frankly, I think it is great the OP is enjoying his ride so much. I loved our old 240 Volvos my wife and I drove them both for 20+ years. Friends constantly mocked us about the "Landing" lights on the front (yes, the headlamps were rather large) and how pokey they were, but we were very happy and contented with them.
Just keep riding your vintage Huffy and let the snobs have their day!
By the way, I test rode a Specialized Roubaix S Works(pricey top line plastic bike) at the Morgan Hill facility 3 years ago and thought it sucked. Handled like a wide load over limit truck. To each his own.
Ride on, bro.
