Not many.
Mine was a special order.
I grew up on manuals.
The last time we bought a car was about 7 years ago. We bought used, and we had to search a number of lots before we found one with a manual. Some new compacts come with a 5-speed or 6-speed, but I don’t think you can even special-order a new 3/4-ton pickup with a manual any more.
I personally started driving automatics, but the first car I owned was a 1966 VW sedan, and once I learned to drive stick, I never wanted any automatic again. Today we own two cars with manuals and a pickup with an automatic (long story why).
My 17 year old drives my manual trans car every day.
