I am considering adding a Kleemann Kompresssor to a brand new 2002 E55. The performance sounds great, and I think I like the old E class model better than the new one. My main concern is having the car serviced & maintained. I live inChicago, and I dont know of any shop(tuner) that would be able to service this car if anything went wrong. Would a local MB dealer be able to service a Kleemann product, considering the new E model will have a AMG Kompressor? This car will mostly be a weekend car (maybe 5000 miles a year), and how much should I expect yearly maintenance to run. One more thing, if there are any Chicago area people that frequent this board could you tell me of any shops (tuners) in the area that specialize in Mercedes.

Thaks in advance for any info provided.
