Not everyone wants one. Plus, an automatic is more forgiving as the gears and cams get bigger. Dialing in a 4spd is an entirely different task, and takes a lot of know how. There's no torque converter stall to change, the direct connection means that if your gear change drops just a feels hundred revs too many, you feel like you're climbing out of a hole to get back into the power..
But at the same time, nothing beats rowing through the gears. I just wish second gear in most 833s was a little taller. The jump to third is bigger, and feels like it brings the party to a halt a little too quick. But that's just me..
