I mean, I chatted with some Daimler guys a few months back (long after the VW scandal broke), and they were laughing at VW's lack of urea tanks (and pointing out theirs on some disassembled trucks at the factory), so...
Though VW is STILL talking about rogue engineers, so you should never underestimate stupidity...
As for market share and brand, I'll admit, my dad has a leased egolf. And throughout the whole thing, he's been like "well, hey, at least I'm not affected". Not sure if he'll go for another VW or not (this is his first). Though I've always been a fan of the Japanese makes (Honda, Subaru, Toyota mainly), so combined with this, I have a hard time seeing myself buy a VW. Well, maybe if they demonstrate that they're doing better quality and being tightly regulated, since Golfs are kinda cool... after all, they *were* basically founded by the third reich, which hasn't been a problem.
