Cars changed: Instead of mediocre crapmobiles that rust and rot, wobbling, squeaking and rattling, down the road, they've become durable, quality pieces. It's funny to see old cars in period-piece movies. Consistently pristine, sparkling and smokeless, unlike the real cars in the 50s through 70s that were clapped-out, ratted-out, rotted out, smoke-spewing and noisy. Hoopties with terminal road rash, barely kept alive -- and this was sometimes after only a couple years of use.
