SLK 55 or SLK 350 manual
New to the board.... My lease is up on my 2003 911 cab.(my second) and am considering the SLK. My heart bleeds for a manual transmission, but the SLK 55 AMG doesn't have one. The 2008 SLK 350 doesn't either according to MBs website. I was hoping to get opinions on what is more fun to drive. A 2007 SLK 350 stick shift or a 2007(8) SLK 55 AMG with the AMG speedshift etc. I was so surprised to see such quick cars and no manual option.

I like the SLK 55s body styling a lot but have never driven anything but a manual transmission. So I hoped you all could give me your thoughts.
Thank you!
On the other hand I do use the paddles in S mode to downshift into a specific gear that I don't want the tranny to shift out of.
What you lose in the form of a good manual, you do however gain in the form of a torquey engine, cool vario roof, and an overall rather nice car that turns heads (at least more then Porsche over here in Switzerland, where Porsches are now dime a dozen).
The 350 manual gearbox (you can get it here, so you just need to haggle with your dealer to get them to provide one for you... it's possible, you just need to tell them that you'll only buy it if you can have a manual box) is quite good for a Mercedes. The shifts are precise and easy to do. It's a bit step up from back when MB manuals were sluggish and boring... Ok, so it's not quite S2000 material, but it's no way near as bad as some would like to make you think it is.
But the 350 doesn't have the power and torque the AMG does, and to get a good level of trim (leather and options), you're better off buying the AMG which has a lot of that standard (at least in Switzerland).
Now, go and bag yourself a test drive. Someone who's been brought up on a stable diet of flat 6 boxer engines, will find the V8 a truly different engine. It might not be to your taste, then again, you might find that the overall quality and features of the SLK overcome the other shortfalls. It's not a perfect car (then again, what is?), but it does many things very well.
I've had the owner of a 997 Turbo praise my car, as I've had an owner of a Lotus Exige, Ferrari 360 Modena and an M3 owner, all show their appreciation for the many qualities of my SLK.
Last year I ask the similar questions between the 350 manual and the 55. I driven a manual for 25 years until I purchase the 55. Mind you I truly miss the manual tranny - SLK55R is also correct about the paddles - I prefer tapping the stick to manually shift. Recently a 350 of the same color wanted to play at the stop light we kept hitting. Obviously no contest, whether I let sports mode shift for me or if i put it in manual. I think the driver wanted to see the power difference between the two on take off.
Now, if you love MT driving and you not looking for kick *** power plant then you may be happy with the 350. Test both, I did, loved both but what got me was the aggressive appearance and the power. We all want more power.
I do miss MT driving - alroumi - as you can see I picked the 55 for the same reasons you mentioned. Would do it again...I'm not even sure. They say you can't go back - one can always find a other brand that has it all.

You could always wait a little bit longer for the facelift SLK which supposedly will have about 296hp rather then 272 (and perhaps a $2000 Kleemann header mod could bring this to 310hp, a number closer to the AMG's).
The 350 does weigh less then the AMG, so all that helps. Just don't buy a 350 without the sports pack (stiffer springs and stuff). The AMG kit gives it a nicer look as well in my opinion. The hood vent 'claws' are a must IMO (standard on the AMG).
The Best of Mercedes & AMG
The Z4 is going back in May and we've decided that we can in fact have a fun car and have chance to enjoy it despite becoming parents and using our 4-door daily drivers whenever we have our daughter with us.
My wife is very stuck on the idea of a manual transmission as we both enjoy rowing our own gears - but the SLK55 just seems to be such a fun car that I could see myself living with the automatic box. I drove one on an autocross course last week at an AMG Challenge day and it's really quite a torquey little monster and sounds fabulous.
But if the need for a manual gearbox wins out, she prefers the traditional long bonnet and short rear silhouette of something like a Z4M Roadster while I would get another Boxster S (had an '01 before) or go to a 997 S Cab and put a Britax seat in the back so we can take our wee one with us in the fun car.
Actually, if I really could have an ultimate drop top toy, I'd get an F430 Spyder in either the manual or F1 transmission - I wouldn't be too picky about it in the case of a Ferrari!

But back to reality...we'll probably end up with a manual gearbox back in our garage come May.

Considering that in 08 they did shift the normal brakes to the OLD C55 brakes ... I would highly recommend the 030 package. I love the CF interior, steering wheel, suspension and the brakes. The fronts btw are 14.2in Rotors!!!
The suspension is a bit stiffer but its still acceptable to me. You need to test drive if it really bothers you.
Also regarding the brakes ... I remember a poll about this before and its the only one(030) that didn't have any one complain about squealing.

I have heard that the wheels themselves are a bit heavier than the stock 55 amg rims. Now don't get me wrong. I'm not saying don't get the package, but you have to ask yourself whether you want a luxury sports roadster or a weekend track car for fun. And IMHO if your selection is the latter over the former, then I would suggest spending money elsewhere on a "funner" car for the weekend but not necessarily as practical as the SLK for an everyday car.
Just my $0.02 & GL with your decision
P.S. I would suggest to Mercedes Benz that they offer carbon fibre or wood trim on the 55. The Vavona wood looks awesome and the carbon fibre even better.
And this has already been reiterated but shame on Mercedes for replacing the stock 55 brakes.
Oh well, I'll have to do with my non-noisy c55 brakes when i get my '08...DISCLAIMER: I'm biased. I'm getting an 08 without the 030 package.

Until you drive yourself the 030 package you really can't comment on how "harsh" the ride is. Personally its fine for me and I love the stiffer suspension. This car is my daily driver and I have put 26k miles on the car already. I've driven to LA which is a 5 hour drive and I'm still fresh when I get out of the car.
In terms of price ... the different steering wheel, CF interior and brakes easily make up that amount. Go look up the prices for a nicer steering wheel, CF interior, and 14.2 brakes ... I'm sure it will add up to more than 6k USD without install.
My recommendation is change your order ...

Honestly have you seen the side by side photos of the 08 and the 05-07(lets not even put the 030 in there)? Just from a looks perspective the 08's with the tiny brakes look totally DEBALLED.

Btw the rims aren't silver plated ... I think your thinking of chrome. They have the same finish as normal SLK55 rims.

man did you set me up...
in the P30 Performance package the MB website says "18" multispoke wheels are finished in sterling silver"...the is silver somewhere in those rims. that may look good on the silver body but not sure about capri blue....anyhow, i want a comfortable ride. Unless there is a mean change in the exterior body, seeing wood and carbon fiber in the interior won't do it enough to have a super stiff ride. . unless i get brake squeal otherwise. then i'll definitely get the P30. oh, and i don't want a deballed looking brakes, that's fo shizzle.

Now some images of 030 brakes ... sorry don't have super closeups like above but it should be clear how big a difference it is. My rears are larger than the fronts for the 08s.
