I expect this has been asked, but I didn’t find what I was looking for when I searched.
is there a web site for how many cars were made by year, and style. Also how many are still around?

 

I don't know of a website, but Setting the Pace has production numbers for Oldsmobiles broken down by model line and style. As far as how many are still on the road, there is no repository for that kind of information.

 

The AACA estimates that after 25 years less than one percent of a typical auto's production will still be surviving . The rest being scrapped .
" Typical " would not include cars such as Corvettes , some of which have a survival rate as high as 50 percent .
Popularity of a model will have a great effect on survival . in 1957 Ford made a few thousand more cars than Chevy .
But you'd never know that by the number of '57 Chevy's you see today compared to '57 Fords .
