yep that is my understanding too the Mark iii which is like comparing a 66 mustang to a 86 mustang. Sure still a mustang but different chassic, body, specs. However there are some marques of cars that did span a large era with only minor changes mainly under the skin aka Datsun 240z, 260z and US spec 280z all S30 chassic from 69-78 there are 6 different bodies I have seen in these Datsun Z cars mainly around chassis rails, tunnel, diff mounting etc minor improvements in design or safety requirements. Also a Austin/morris/rover mini is basically unchanged from 1959 to 2000 again changes for safety or under skin improvements but basically same suspension, brakes, engine configurations throughout that range.

That can't be said about the carpi a Mark iii is very different in look and specs to the mark i.

If you have a set of rules you should stick to them and not make a rule and skip it for x and enforce the rule for y.
