I don't own a 462, but looking at the Stihl website, the 462 appears to be a unicorn. There is no 462C, which is weird as the 462 has all the comfort features listed. So the "C' is implied in the manual carb model 462.
The 462C-M is the M-Tronic version which follows the traditional Stihl pattern where the C indicates comfort features.
Whereas the 362 manual carb model has no comfort features listed, and you have to buy the 362C-M to get them.
What the heck Stihl? That's damn confusing.
So what's for sale here appears to be a 462C-M per the Stihl website. I'm not contradicting what Matt has said, he certainly knows what he's selling and his word in final.
Sorry for the tangent... take it as a free bump.
Edit: damn Kevin beat me to it
