Here's a photo-essay showing the evolution of classic to modern cars. Some show very little change, mostly a more streamlined form for less wind resistance. Others are completely different. That's a problem if you liked and could drive the earlier versions and now can't get a vehicle you can drive. Same with the rush to electronics; people with a more mechanical approach are out of luck, as are people with low skill at computers and machines in general. Earlier cars were much simpler. They didn't do the gee-whiz things but they were often more durable and easier to operate. One of the few innovations I really like is automatic transmission. Outside that, I have found that the drawbacks of new technology usually outweigh the benefits in cars.
