Idk, every Delorian I’ve seen still looks great! Granted, there’s probably a lot of survivor bias there. But if you take care of it, stainless steel lasts forever.
I agree with you - they do look great indeed. Regarding survivor bias: those cars you see around probably are maintained well. With a sufficient level of maintenance, even a Yugo can be kept in pristine condition (given the supply of spare parts in this particular example).
When it comes to Tesla in general, many people complain about insufficient panel alignment, although it its barely noticeable. But given the pice range (this is a upper class car) one needs to pay to afford such a car this issue shouldn’t be present. On the other hand: when I look at my car (Mitsubishi Mirage) closely, the panel alignment ist’t done well either. But considering the price range that car has been sold, I can live with that.
