Big performance advantage from 7G auto!
Info from Autospies (sorry if this is old news!) suggests that the auto box will be much faster than the manual when overtaking:
"From a standing start, the SLK 350 reaches 100 km/h in just 5.6 seconds (with the 7G-TRONIC: 5.5 seconds) and accelerates from 60 to 120 km/h in 8.7 seconds (with the 7G-TRONIC: 5.1 seconds). "
Can the auto really be 3.6 seconds faster in the 60-120kph dash than the manual?

I'm sure the 7G and other AMG auto boxes are great but I thought the main reason for AMG only having autos is that MB haven't been able to build a manual to take the huge torque that AMG engines produce!
Given the choice I'd much rather have a manual than a semi auto because changing gear is part of the fun of driving..... I'm just hoping that the 7G on the 55 is good enough that I won't miss a manual box.

Best cruiser SL55 AMG
Best track car Formula Palmer Audi (single seater with slicks and wings that has a power to weight ratio of 600bhp/ton!)..... as quick as a McLaren F1

The Boxster suffered similar abuse (but not as bad) with people being jealous..... I only get positive coments while out in the S2000 so I'm hoping the SLK will be similar?!

Tests of in gear times are usually in one gear for manuals and use kickdown in autos - hence why Autos often seem much faster than their manual counterparts. The 60-120kph time for the manual is probably only in top (5 or6th) gear. When you think about it its a meaningless comparison as in both cases you want to floor the throttle. It should be a test of mid range punch, and how well the car will accelerate in gear, but for autos its a bit pointless.
PS I had an E46 M3 for 6 months, and thought that the SMG gearbox was fantastic. You do need to get used to it, but once you do its great. I sometimes wonder how long jornos who dismiss SMG type boxes have actually spent driving them and properly getting used to how to drive them smoothly. The SMGII M3 can certainly be driven quickly and smoothly, it just takes practice, and a certain technique to lift off slightly during up changes. Also, I never had any negative reactions in mine, or in any car for that matter - perhaps its how you drive, rather than what you drive.

Where in Euroland are you?...... I'm based in London and the M3 got a huge amount of flak...... I didn't drive it any more spiritedly than my S2000 but still got loads of grief...... and I've NEVER had any trouble with the Honda (in two years) even though its nearly as quick and much louder.
You're right about learning to drive the SMG smoothly...... by the end of the time I had with it I had realised that it didn't like flat throttle shifts and that you had to lift off as you would in a manual.

Thats exactly it. The SMG is jerky if you don't lift off during normal upshifts (though its OK not to lift off for full throttle S6 changes at the red line
).
What always makes me chuckle is that manuals require just the same finesse to change smoothly - jornos don't say, "oh this manual is rubbish you have to lift off when changing gear", and yet any SMG type box requiring some throttle skill is somehow bollocks.
I'm in the south west at the moment - ooo arr.
