      In the Rabbit (rev hang, terribly spongey mounts) option 1 is the smoothest.
      In the CRX option 2 is the smoothest.

      Assuming you're upshift rev-matching, I don't get why people think option 2 would be less wear on the clutch.

      With 2 you're slipping the clutch with each upshift, which does it make it smoother (less shock from just releasing the clutch), but means more wear, no?

      I go with number 2 in the b6 a4. Also is resting your hand on the shifter bad for the synchros? I read somewhere that it is bad.

      Bad for the TOB.

      Leaving your hand on the shifter has absolutely nothing to do with the throw out bearing (if that's what you meant by TOB)...
      If you do method 1 too slow (which I can only imagine you would be, if you're actually thinking about it) chances are the rpms drop way too much between shifts. When you let the clutch back out it'll slip all the way back to where they should be. Furthermore as someone else said, the engine braking will lead to a pretty sloppy shift.
      In normal driving I only use the clutch when re-engaging the gear. If you dont load up the trans too much (no acceleration or deceleration) it pulls right out of gear without clutching in.

      I have heard this before as well, i think it depends on what you call resting, if your elbow is on the center arm rest i think its ok, if the weight of your entire arm, then no

      On your ti?

      I think my 318ti's 2nd gear synchro is going out. Sometimes when I shift to 2nd and it feels like it engaged, but its actually not. Then, when I try to push the gear into 2nd completely, it grinds.

      Actually on my jetta

      ti trans can take a beating for the most part and not run into problems at least from my experience and what I read about others.

      I think mine is closest to #2.

      #1 seems really clunky and it's just not really how it's supposed to be done.

      #1 in my Subaru and #2 in the bimmer. It also depends on rpm. Higher rpm shifts tend to feel like #2.

      Not so, if you get the timing correct. Simultaneously disconnecting the clutch as you are taking load off the engine (releasing accelerator pedal) means it's not slipping on the first step. Re-engaging the clutch after the engine has come down in revs during the shift to roughly the same speed, so that there is not a major step in engine speed that the clutch has to take up, means there's absolute minimum slippage on re-engagement. Done correctly, the gear change is very smooth with next to no slippage.

      I've put 400,000 km on two different manual transmission cars and never had to change a clutch. The Jetta is going to need a clutch soon, but only because of the crappy DMF mechanism (which wears itself out regardless of what the driver does).
