IMO on this subject...

The Auto Trans in the Xfire is the same in the CLK & SL and most of the faster Benzo's... They dont even make some of those cars in manuals... sorta like the Xfire SRT-6... there is a reason for that....

People say the manual is faster... but after chipping... and brake torquing like WM has taught us... you can pull off the same 0 - 60 times as the manuals... since chipping takes your RPM to 6200 instead of 6000 for shifting.. give it a bit more power...

I love my touchstick and wouldnt trade it for a manual at all in this car... would be different for different cars... but for the Xfire... i love it!
