Reasons to buy a C63 over an M3?
The main advantages I see the M3 having over the C63 are:
-Option to purchase an extended leather dash, which in fox red looks amazing. (I think both cars interiors appear cheap, but this option really helps.)
-New 7 speed dual clutch transmission (0-60 times about the same as C63)
-Option for 825 watt 16 speaker audio system (I am an audiophile)
-Option for Electronic Damping Control for a more comfortable ride
-Better highway gas mileage
-Limited slip differential
-Launch Control
-Availability of many aftermarket parts
I really think Mercedes needs to "step up" the C63 if it wants to compete with its competition. I really had my eyes set on the C63, but the competition just has so much more. Anyone agree?

not a 7sp DCT only a 6sp dual clutch
no launch control on the 6sp manual M3.. probably will be one on the DCT. But remember in the US (like the M5) you are probably going to be limited by this.
The 4.0L engine is new to M line up.. the 6.2L has way more development at this point
Without the P30 (sport package) the C63 will ride just as the base M3. But having 3 modes of ride preference is an advantage, but will cost you as an option.
The M3 is a great car.. but you will need to the M drive, EDC and need the navi for all of this... and price balloons.
The C63 at the base prace without all the goodies will be a great car.
Torque: As some writers have noted, you need to drive the M3 like you stole it to know you have power.
HP: no argument there, C63
HIgher Trap speed (7sp vs 6 manul) this can possibly change with the DCT. But depending on the gearing and the additional weight of the new transmission.
LSD: Well you can opt for the P30 or just wait to buy one from AMG.
MPG: M3 averages better.. but again you have to drive it hard. The AMG you can cruise around in high gears with not problem. I can acheive 22.5 MPG on my E55.
The biggest thing for me is this, the 6.2L is detuned. How much? we don't know.
If the marketing material is right, and the C63 is only putting down 450+hp.
Getting to 525 will be not very difficult. (bigger airboxes, tuning and probably some exhaust tuning)
Not sure if you are going to be able to squeeze another 75hp of the 8000rpm reving M3 at this point, unless you go force induction or spend serious $$ for headers, ECU, cams, throttle body, CAI, exhaust.. ect.

The Best of Mercedes & AMG
Honestly, both of these cars are fantastic automobiles. I think for me, the deciding difference will be made after a test drive in each.

BMW has stepped up, Audi has B&O... When is MB going to get something decent? People will pay for it in a second because going aftermarket is a joke on german luxury cars.
for looks within the car the extended leather helps
7 speed DCT is suoerior to c63 since both are auto's but m3 is a faster auto thru dual clutch, like audis Stronic/dsg
The new C63 should look great in black/grey but did not like it in white at the NYC auto show
I think it is personal preference but I like the m3 over the C63 for adjustable suspension and DCT
...and honestly I'm not too impressed with either interiors for 65-70k, I personally would rather just get myself a slightly used 07 E63 or an 05-06 SL55 if we're talking two doors for that kind of moneyThe 335xi coupe + Vishnu tuning would work best for many people living in bad weather areas and using the car as their DD and for around 55k (without mods) and 60s with mods
What I really dislike is the fact that the C63 has ballooned to over 4000 lbs. It's hard to cheat weight.
The fastest 335 so far was able to edge out a pulley E55 with 20's and only putting down 400RWHP.
That would be Walk U's E90 sedan that has all the mods available.
The E55 had a pulley and FM HE, but for some reason its not putting the power as it should.
In fact the 335 could not hold boost for 2 runs and lost but once it was able to hold 15lbs it pulled the E55 by 1 car before the E55 had to abort.
So you see.. even a FULLY modded 335 will have issues on the open road.
You are barking on the wrong tree my friend.. and you definately not sounding very educated on your responses.

yet to be tested on american soil.. at least to my knowledge.
I search daily for info.. and I have not seen any tests yet.
Maybe in europe.. but those test have shown the C63 faster in all categories, in terms of speed.
There have a been a few test that the M3 has done well. But in general the C63 is faster as the speeds increases.
Being ahead by 1 second to 100 is a big lead... being ahead by 2 seconds by 150 is a bigger margin.
sort of the lead the M5 would put on a stock E55 to 150mph
