Old To New Platform/ Next Car Designer Update

In the finished game would it be possible to build a 1990s hatchback and use the same design in 2010 for instance??? but with certain tweeks like any updates that a car would have over the years. Or have a 1940s platform and use that in 2004?
As for the car designer when is the next update and what does it include. Im hoping new body designs and fixtures, also as my laptop is not built for gaming the FXAA setting is turned off but the car designer is still pixelated
