curious...would the C230coupe (I guess 2.3L '02) have been more beneficial if it had
If redline in second gear was above 60 mph that would shave a couple of 10ths off of the 0-60 speed (instead of having to do a 2nd-3rd shift at 54 mph). Quarter mile might be less too - depending on where the shift points are.

auto vs manny
the mileage not neccesarily very different. while the auto tranny absorbs more horsepower but its very smart in using the lowest gear you always find yourself cruising around streets at below 2000 rpm while in manny you are too lazy to shift to highest gear to save gas you just remain on 3rd or 4th while you could have use 5th or even 6th gear in around the city
5sp vs 6sp
on paper 5 sp might be better coz on the 6sp, 2nd gear only goes up to about 52mph then you have to shift to 3rd to get 0-60 times where you probably lose what half a sec or 1/4 sec there so 0-60 time suffer. if you compare 0-50 time the c230k is very competitve while 0-60 time might seem slow. It's not a surprise if the coupe had the 5sp it could go 0-60 under 7sec easily.
on 1/4 mile you might lose some time if you had to shift for extra gear depends what is your trap speed i think stock coupe can go about 85-90mph trap
One reason is marketing. For some reason, people think that they are getting more by getting 6 gears instead of 5. I see some people amazed that it is a 6-spd, like it must be something special since it has 6 gears. I don't know if this is enough for someone to base their purchase on, but it can't hurt.
IMHO the coupe doesnt come alive until like 4th gear and up where it really shines

if they really wanted to go all the way with the 6sp they could place the gear ratio in such the way that it will produce better 0-60 times say 6.9sec 0-60 14.99 1/4 mile time.

I think a taller rear gear would help since 1st is so low. It is a lot easier to change the rear axle ratio than the transmission ratios. Then you might be able to hit 60 in 2nd.
Remember, this is a German car, built primarilly (first) for sale in Europe and Germany. Perhaps it has 6-speeds to make it more flexible on the high speed Autobahns, Autostrada (Italy) etc.
I don't know if the ratios are the same in Germany as they are in the US, but I would think a sixth gear in Germany stresses the car less while running 20-30 min stints above 100 mph.
Here in the states, I agree that a 6-spd is needed for Marketing reasons. F1 cars have 7 spds. It won't be long...

Here's a link everyone should read: http://www.howstuffworks.com/transmission1.htm
The performance for 0-60 or 1/4 mile has nothing to do with whether it has 5 gears or 6. Its all about the ratios.
1 (4.46), 2 (2.61), 3 (1.72), 4 (1.25), 5 (1.00), 6 (0.84)
