Reasons to buy a C63 over an M3?

I have been following the C63 from the beginning. From the spy pictures to the speculation on the power. I put my deposit down last October as this was supposed to be the first AMG car built from a computer model. It was supposed to be an M3 killer you could say. Now that it is arriving this month, after comparing it with the M3, I cannot see a reason to purchase the C63 over the 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?

Looking for a new toy.
With all due respect, some of your deciding factors for 2 ultra high performance vechicles are: leather dash, high end stereo, comfortable ride, and gas mileage?

0-60 ?? you are really focusing on the wrong performance stats right off the bat.

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.

2005 M3
The M3 loaded with Dual CLutch extended leather, etc will be close to 70k if not more. Im seeing alot going for 69k without the $2700 dual clutch tranny option. C63 is 63k loaded...and around 66k with the performance package. An M3 may be faster around the track, but lets face it in the real world, in my e46 M3 with coilovers gets beaten by my friends e55 on the highway to any destination. Gas mileage wont be that much different when you rev the M all day long. Plus I can't get over the fact that a chipped 335i can go head to head with the M3.

I was approaching it from more of a luxury AND performance standpoint. I know in a few other threads people are claiming the C63 lacks in luxury.

The M3 your talking about is going to cost roughly 73K+ compaired to the C63 loaded for 63K. You can buy 10K in mods if you must but when you line up at the light with your M3 do you think your going to beat the AMG beside you. On your Radio issue either cars factory system is decent but to get a nice one you have to go after market. Why pay BMW for their crappy stereo. I know in my AMG id have it off most of the time and the windows down just to hear the exhaust. Maybe you could get a MP3 of the C63 and play it in your M to make it sound good.

I agree with you guys that the M3 fully loaded is around 70k, more than the C63. Initially I believed the C63 would spank the M3 off the line, but news of the DCT tranny with quicker times is leading people to think its going to hang with the C63. Guess I'll have to wait and see.

I would hope an E55 is faster than an E46 M3...but yeah there are chipped 335i's running around with 460 lbs of tq!

a quarter mile at a time
Looking at 0-60 times on these cars are uttlerly useless IMO. Both of these cars are very traction limited to 60mph. Looking at trap speed and anything above 60mph and the M3 is quite a bit slower.

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

The M3's optional audio comes from their Individual program so its supposed to be top of the line. By the way, the last line you wrote is hilarious!

The audio options mercedes provides really are disappointing...

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.

The orignal poster seems to have researched M3 a lot

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

4 door vs 4 door, the C63 looks better. That's enough for me. The other intangibles are too similar to call.

Agreed...that's why I'd take the M3 coupe over the C63 ...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 money

The 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

The C63 will eat the M3 for lunch on open roads. The real advantage that the M3 really has in still in the handling dept.

What I really dislike is the fact that the C63 has ballooned to over 4000 lbs. It's hard to cheat weight.

Then don't do it. When in doubt don't spend such a big amount of money.

At least test drive the car(s) for heavens sake.

but those chipped 335's are just not ECU alone. Its exhaust, down pipes, CAI, and race gas. Hardly your everyday car and not covered under warranty.

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.

its only speculation..

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

From the numbers I've seen, once past 100mph, the C63 is much faster.

Interesting thread for me. I have gone back and forth over these cars for months. I'm not ordering until mid-summer. I'm leaning towards the M3 because of the EDC and the manual transmission. I like the looks of the C63 better. I prefer coupes in general. The fact that the decision is a tough one means that the competition is close.
