Steve welcome to the forum. The guys here are very knowledgeable and will give real hands on help with all Triumph matters.....plus anything else!
I agree concourse cars can be a pain. I took over two years to achieve a concours E Type and sold it 6 months later. Two frightened to take it out the garage. Sold it and bought a good useable TR3A and loved it.
I have a Mk2 Vitesse saloon, the roof keeps most of the rain out but gets a bit toasty in the summer. Saloon would still be my choice
