My Sport was my commute From Cambridge to London on a daily for some time. Snow on the Conti's great fun. On the Avon's that's a different story in snow!
If I had some spare wires I'd go for:

It's a different type of car you need to fettle with, not the engine but the body soft top (winter), loose screws (summer) Grease front suspension when it rains. But the engine/ Gearbox is Modern and other than oil changes is like owning a Focus!
Now as for Indicators and brake lights, number plate lights, they are all retro Lucas and last like a 50's car you soon learn to change bulbs and fix earth wires clean contacts!
