Yup, it's amazing where consistency will take you these days. Essentially since the mk5 days, so spanning well over a decade, small incremental changes have gotten us 3 generations of the GTI without glaring flaws (well, timing chain tensioner aside).
The Si has had a few misses, and made one of the most polarizing cars in terms of design with the most boring drivetrain in the 10th gen. Brilliant car by any measure, just not what you'd expect out of a Si.
Fiesta ST is fun but short-lived on these shores.
