Dealer says my MBenzNL lowered car was un-alignable
It's nothing to worry about. I personally wouldn't have a dealer align my car as they really don't know what they're doing outside of "spec." Find a good performance alignment shop so they can get your toe and thrust angle settings right. The negative camber is just something you'll have to live with - one of the prices of having a lowered car.
Where do you live? If you live in northern California, I took my car to Freeman Frame and Alignment in San Jose. My specs after lowering my car (about 2") were:
camber: -2 front/-3 rear
toe: I forget, but way out of MB's recommended range.
New numbers:
camber: -0.5 front/-1.5 rear (MB recommended range is -0.5 to -1.5 on E500)
toe: 0
They can set your camber/toe to whatever specs you want. Initially, I had them set my camber to 0, for max tire durability, but did not like how it handled...brought my car back, and had them set some negative camber.
If you're not able to adjust your camber, have the alignment shop reset your toe, as this is the bigger contributor towards tire wear.
Good Luck

The rear camber is adjustable, just need camber bolts if I remember correctly. A bit tired right now as I just got back from up north.

My understanding is that rear camber is non-adjustable on mercedes. I could not find any aftermarket camber bolts for my car.
Your toe is much easier to set than camber. I was told by my alignment shop that he has seen Mercedes with -2 degrees of rear camber, but with 0 toe wear out their tires evenly.

Most people dont even know these bolts exist. They also go by the term "crash bolt" since they were designed to make cars that were slightly bent in crash align back to OEM spec.
Good luck and tip the dealership in on the camber corrrection bolts.
The above poster is mistaken in saying that the camber or lower control arm is not adjustable. Have fun!

Can you post pictures of the bolt and its location?
My own C250D is way out of alignment specs as well (too low) and has been like that for 500.000km - nothing to worry about other then that tires wear "slightly" uneven (the price of lowering).
greetingz,
............when a car is lowered, you can have a problem with doing an alignment for the following reason. The less expensive alignment shops use a device that uses infra red beams across the axel and these beams require line of sight. With a lowered car, the line of sight can be obstructed. The option is you have if you still need an alignment is to to to a performance shop that has radiofrequency alignment.

greetingz,

The rear camber IS NOT adjustable on a 211, without an aftermarket solution, if one is even available.
There are several types of rear camber bars for the W211..So One can adjust rear camber...Hop/Speedy Benz/Renntech all Make them!
I Would say the tech saw that the car was lowered..and Did NOT even rack the car to see the (BEFORE) specs...

........In Atlanta, this problem can be easily solved by going to Butler tire. They do alignments in lowered and modified cars including my extremely lowered CLK. Butlertire.com have a radiofrequency alignment machine that solves this problem. That is where I had my lowered CLK aligned. To find a similar shop in Texas you may wish to contact them at 404-303-1114 for a recommendation. Here is a link to their website. LINK
