1963 Triumph Herald 12/50

Best thought of as a GT version of the Herald 1200, the 12/50 has become the most popular saloon version as it combines the prettier looks of the early cars with almost the performance of the blander Herald 13/60 that replaced it. A higher compression ratio and other tweaks took power from 39 to 51bhp, disc brakes were standard, as was a Webasto folding sunroof. A fine-barred aluminium grille and ‘12/50’ badges were the only other external giveaways, though you did also get a padded dashtop. Perhaps due to the sunroof, Triumph never built a convertible version.
