I'm not old but most of the Buicks I like are.
As for this thing, I'm not sure what I think. It looks very "conceptey" and not really remotely production-ready. Way too low-slung and wide for a production model, which means if it DOES get built, it'll be diluted, its waistline will go up and its sex appeal will go down.
The rear looks like a 4th gen Eclipse.
That is not a good thing.
The rest of it is certainly graceful, but not particularly unique. It has a Ford grille and Audi headlights. The nose actually looks sort of Tesla-ish.
I do like that the lower front bumper is not a mess of black plastic and gaping scoops like every other car right now.
It has fender vents.
Why are fender vents still a thing?!
Yes, I know it's a Buick.
No, those aren't trademark classic three-hole vents! (Not that I actually like those any better on any modern model).
Basically:
It's not ugly at all. It's quite nice. But it doesn't do anything to get my blood pumping. It certainly doesn't make me think "Buick." Which I guess is a good thing, but if that's a good thing, well...that's not a good thing for Buick.
OH, and it'd probably be FWD anyway.
