C15 and T15+3

[jeh]

Any difference between these two besides the body style?

Also, what does the +3 mean?

Nope.

Also, what does the +3 mean?

Festool boasting. The 3 means the drill is as strong as a drill from the next voltage class. If you have a 12v Festool drill it's supposed to match 15 volt drills from other manufacturers, and a Festool 15v with 18v from others.

It's not really true though.
