I watched the first episode of the Jetta series and found it quite lacking, it's more suited for the 50yo midlife crisis type owner than a 20ish petrolhead.
They did a "suspension upgrade" with no real mention of what exactly they did and then the fat dude got in the car and did half a lap with a "yep its way quicker" their was no mention of laptimes etc. Same with the power mods they have done, no initial dyno readouts etc its just a simple "yep it goes faster now".
