What are some "must have" accessories?
 

What accessories did you get right away? This is on my list so far:

All Weather Floormats
AMG License Plate
AMG Valve Stem Caps
Mobile Phone Holder
AMG door pins
Cargo Area Tray
Clear Bra

Not sure how important audio quality is to you, but I added 2 JL audio 10" subs and an amp to my 09 C63. They complimented the factory Harmon kardon speakers very well. I felt the factory sub was under powered and produce poor quality bass notes.

Best accessory modification is the one to the person behind the steering wheel. A couple of weekends at high performance driving event with an instructor. Best fun and best investment ever.

Nothing on your list is a must have unfortunately IMHO. Wider rear tyres are #1

All I've done so far is get some semi-slicks. Personally I don't really want/need anything from your list. Maybe the floor mats.. maybe.

best accessory? A gorgeous hottie sitting next to you in the front passenger seat.

I recommend it for any car, not just the C63

Be careful with the AMG valve stem caps if they are metal - they will seize on the stem and potentially crack your TPMS. It's why they all come with plastic caps now.

If you ask maverick; definitely a supercharger

Why 2 weistecs and no xtra power

Radar detector?

tinted windows, front license plate delete

This is an example of one of the 'must have' accessories that goes very well with our cars, IMHO:

Here is my list of recommendations:

All Weather Floormats: must have
AMG License Plate: for rear, you might have problems bending it for the front.
AMG Valve Stem Caps: no, just something that easily get lost.
Mobile Phone Holder: no, and it only invite thrives and break-ins.
AMG door pins: must have, but try to get OEM parts.
Cargo Area Tray: must have.

In addition:
C-Class sun screen
Car cover
AMG center control knob cover
plus a NICE towel for your husky

What's a Cargo Area Tray? Is it just another way of saying "Cargo Net"?

No, it is not a net. The cargo area tray actually covers your entire trunk/boot with a plastic tub. It cost a bit of money but it's worth it. I only have the cargo area liner mat and it doesn't work too well.

Bigger rear tires
Tune
Coilovers
Rear diffuser (stock is cheap looking IMO)

color matched or clear reflectors if ur in US

is the weathertech equivalent cheaper cost wise? nm, just clicked your link for the liner.

seems to be just as good fit as oem.

Looks fine, but it's only a $5 difference so I am not sweating it.

you save 5 dollars here and maybe you go somewhere else, maybe you save another 5 dollars, then you have ten dollars

:D sry Russell Peters is top of mind atm lol

A replacement shift knob:

i got the weathertech one over the MB one. i think its nicer and the fit is perfect

haha yea i noticed the difference after and was too lazy to change the post :P

Yep, maybe not a "must have", but after you add it, you'll wonder why you put up with the crappy plastic factory knob for so long.

Actually a bikini clad Thai girl in the passenger seat beats all the above modifications hands down (pun intended)
