As per the article: “The only parts that will be changed are "safety-critical" parts, although in some cases the workshop will fit new body panels. "Sympathetic upgrades", such as improved cooling and Series 2 brake callipers, can also be fitted.”
This general rise of modern-vintage blended vehicles is quite exciting for anyone who is a fan of stylish cars. Modern cars (except for the odd Aston Martin or Ferrari and sometimes not even then) I tend to find look a bit boring. Somehow they never quite match the look of their past greats.
