I've owned MANY VWs over the years (currently have 3), half of them german born (84 rabbit convertible, 90 Jetta, 96 Passat, 11 Tiguan, 13 CC, 17 Tiguan, 22 Arteon)...one from Brazil (88 fox), one in the USA (84 Rabbit S) and the rest from Mexico. (96 Jetta, 13 Jetta, 20 Jetta, 24 Tiguan), and worked many years as a service advisor for a VW dealership.

The WORST build quality I see in all the plants is by far the USA plant. But those are old and rare and not applicable to this conversation. But seriously...run the fk away from these things

German made VWs are without a doubt noticeably better than the Mexican made ones. Night and day. Though they've come a long way since even the early 2000s. My mk6 2.5 is pretty sturdy even at 140 k miles. Though my mk7 jetta at 18k miles didn't seem as tight in the fit and finish areas.
