Newbie - advice: C55 or B7 RS4
Links to where or just you valued feedback.
Planning to purchase a new car in the next 6 months - getting married, planning on family etc. so the 147 GTA isn't going to cut it...
I understand the merits of both cars, but would like your feedback:
1. If you could chooses between the 2 which one & why
2. If you currently have the C55, do you ever wonder what the B7 RS4 would have been like
3. Had the C55, but now have the B7 RS4 - Why?
4. If you have BOTH, which one?
5. Or should I wait for the new C63?
Oh, they are very similar in $$$ here in Australia & I don't intend doing any track work.
Thanks in advance...

If I need AWD car, no brainer and no choice - RS4.
If I could wait for C63 (it should come out in about a year, right?), wait fro C63... I think RS4 would have a tough competitor.
If I would like to mod the car, get RS4 due to F/I... it'd be cheaper than modding C55/C63... but I'd spend similar $$$ (assuming aussie's price difference is similar to US) to getting E55... so I think I'd go w/ E55... bigger, as powerful and most bugs sorted out - plus no aftermarket mods, so no issue w/ warranty.
In deciding between the B7 RS4 and W203 C55, I would consider the following things:
The RS4 is hands down faster in a straightline and on a track. The cost for this performance is that the RS4 uses a lot more fuel than the C55.
The RS4 has less interior room for passengers in the back than the C55.
The RS4 has a manual transmission, while the C55 has a manu-matic.
Do you value the benefits of AWD? Launching the car is easier with the quattro, and you get more security in all weather conditions.
In most markets, the RS4 is significantly more expensive ($94200 vs $73600 in Canada). If the RS4 costs the SAME as the C55, that's a huge bonus!!!!
Finally, which car LOOKS better in your eyes? Most people think that the RS4 interior is quite nice. The exterior of the RS4 is also more aggressive looking than the C55. Some prefer the more aggressive look, while others appreciate the more subtle appearance of the C55.
And nobody really know what the next C-AMG car will be like....so you can wait for it if you have the patience.

PS: I wouldn't wait for the C63 if I were you. Another year before it's introduced in the US, possibly longer in Australia, and you should probably wait a year after its introduction to make sure it's a relatively glitch-free car. And it's not like the E63 is exactly setting the world alight vs. the E55.
The Best of Mercedes & AMG
High Revving V8, 4WD (unless you prefer RWD for power slides
), Aggressive Looks, Manual Transmissionproblem is.. it's more expensive than the C55 here. So if it's the same price for you ... your choice

I prefer the C55's interior though and the W203's exterior is very elegant.

maybe a lil off topic but video of the RS4 vs M3 by Fifth Gear. Pretty sweet video

@ DragonAMG
A new C55 is approx AU$161K
A new RS4 is approx AU$165K
A new E55 is approx AU$226K
All the above is before tax (GST 10% + LCT 25%)
For now, the E55 is not an option
@ PC Valkyrie
I like the sleeper look of the C55, the RS4 just looks liek a body kit.
I do I like the AWD aspect, though I would prefer a auto/tiptronic - city driving!
They are both plenty quick enough...
Both the interiors are great - though the RS4 is more sporty, while the C55 is more luxury/comfort
As I have been driving performance based cars - such as my current GTA - my next step is for a luxury sport sedan, with the emphasis in luxury & comfort.
As previously mentioned, I will not be doing any track work or looking for street modified cars to race etc.
The issue is to now find the compromise - also as I am getting married soon (planing for a family etc), hence I thought the C55 would be a good match...
The only issue now is that, I have been told that Australia will never get the C55 wagon but will be getting the RS4 Avant - BUT then, the RS4 will always be a manual (& my SO only drives auto!)...
Maybe I should investigate a S4 Avant as that comes in a Tiptronic...
Back to the drawing board...

If you don't take the RS4 up to (or near) its redline , and let's say "short shift it" in the 5.5K - 6K range, that car is not going to be much faster the a C350! No, I'm not kidding and not exaggerating. That RS4 engine reaches its HP figures through low torque, high RPM, so with its short gearing needs to be wound-out to be best utilized. ...so just something to consider... Me, I luv high RPMs and I'm always taking my engine up there -- additionally however, my W202 w/a 5.4L Motor pulls like a monster from 2K too, so I can be happy with the transmission left in the next higher gear then optimal for power, because that engine just pulls like few others from so low. You might not like very high RPMs tho. If you're a torque adict, go for the C55.

But, it sure must be fun to drive!
IMHO it's this that's fueling the horsepower race that seems to be a growing obsession for German prestiege marks - to be credible you need a headline grabbing power rating ...no mention of torque in there.
To get the high power without forced induction (in the mould of the BMW) you need to make the big capacity engine rev like mad. Simple as that.
So many new sporting cars are engineered in such a way that lends them better to track use than road use, despite the fact that most never even see a track let alone put a tyre on one. Even AMG are following a similar route with the new '63s' - nowhere near as much torque as the 55Ks but with more power.
That said, after years of SUVs being designed for off-road use first and on-road second, most of the new breed (X5, ML, XC90, Pikes Peak, etc) are all road-focussed first, and off-road second. So maybe things will go full circle with sports saloons too?
My two penneth thrown into the pot!!
