Yes, i do agree. To some extent, cars aren't made the same way anymore, simply because the rules (very litteraly) have changed. Theese days the heap af regulations the good people building cars gotta follow is huge, which ofc. puts some restrictions on the creative liberty one can take.
Another reason I think the conditions have changed is the fact that building a car today (Because the strickt regulations) is rather expensive, atleast when compared to the huge behemoths that the the automotive industies, with their platform sharing and co-op developments. Yes, alot of people get to do it, but it usualy ends up being exclusive supercars like the Koenigsegg or the Pagani you don't really see newcommers who cater to the general public. (Atleast not in my(our?) part of the world)
I do believe that if we were to travel to more eastern seabearings we would come across a totally different automotive culture (Japan excluted) where classics are being born, which we might never hear of.
Allthough, thats not to say that classics aren't being made today. They are, they are just far in between. Imo the Ferrari 360 would be a good example, allthought at the moment i can't think of some cheap cars which might one day be classic. I might return upon further mindstorming.
