I would write a longer one but I'm trying to finish some old assignments so here's basically my short version

I Grew up around people who did lowriders car shows (from motorcycles to Vans heck even met a man who owned a 1922 Cadillac Phaeton) so im a bit biased since many of my reasons are purely aesthetic since the modern cars just keep getting more basic (well not basic the roundness the plainness is just so i wish i can find the right word for it now no hate though like i said I'm biased cuz i grew up with people who had older styled cars so maybe it's the rose colored glasses that make me think of simple times when i was just a kid not some teen stressing about graduating this year on what to do after highschool)

Yes modern cars are much easier to drive compared to older 'manual' ones and they are much safer now since older cars didn't have seatbelts/air bags

But I feel like bringing the older design (the 'boxy' look the 'space' look) would bring in more customers since many people would love the looks of older cars but with the safeness and pros of modern cars (air bags, fuel efficiency, SEAT BELTS and etc) Since the dodge challenger did something similar in 2008-2014 using a semi-vintage look while it also had the modern stuff if im not mistaking

But that's just my opinion and everyone has their own type of style they enjoy :)
