It isnt shocking at all to me. I also own a cuore and i know its that old but the thing is that the shape maybe old but still when u buy a new cuore all parts are brand new and not 20 years old.
If you want to get more shocked, check the model of mehran as storm has said, its a 1979 model.
and also check the model for potohar jeep, bolan, and also cultus , i saw the cultus in this shape in the early 90's , they came in the same shape of two companies , one was the suzuki and other one was chevorlet.
Toyota is also doing the same keeping one model in production with itzy bitzy changes for 10 years.
Nissan is also doing the same. Check out the new models of nissan.
As far as honda is concerned , its only 6 months to 1 years late in producing its latest model.
