Anyone else riding a triumph for regular transport?

I have been using my 1970 Triumph with 1979 T140 motor for my regular commuter. Observations on doing this, the old Triumph is more fun than my new one, gets better gas mileage than my new one (47 MPG), Uses cheaper tires and they last longer, uses cheaper chains and they last longer, old gets more attention and sounds better. The old bike has been together for 23 years and has over 40,000 miles and has never been apart in that time. Will admit that the pistons are a bit noisy in the morning though.
