You're missing the point. Between increasing belt-lines, fatter pillars, thicker doors and smooth/aerodynamic and rounded shapes modern cars have less space than older ones of equivalent exterior dimensions. Because people want a baseline amount of interior space in any given class of vehicle the vehicles have grown. Look at the new iterations of compact cars and compact trucks (and their counterpart SUVs) for a good example. They have nearly identical interior dimensions and have grown a couple inches in every direction and a couple hundred pounds. Just because you feel your car is a good deal for what it is does not mean it is not also subject to the same regulatory treatment. An '03 Ford Escort wagon is 10" longer and the same width and weight as your car and blows it out of the water in terms of usable interior space (I could only find a spec for the 2dr coupe but it has 92.x cubic feet vs 97.x for your Fiesta hatch). It's slower and gets worse fuel economy and doesn't have bluetooth but that's just a reflection of the state of tech at the time. Pretty much every product line has received this treatment over the last 20yr. Your car would exist without modern safety/fuel economy regulation. It would just look like a 2003 Ford Escort that puts down performance numbers that are more befitting the year 2021.
