I just recently bought a 2002 300m Special/dark sapphire blue/black interior , and it passed emissions testing (as like new readings) , with only having replaced the sparkplugs. The car has 237,000kms on it and is in completely original condition. Being the second owner , the original owner obviously had it in a garage since new and took good care of it , without needing anything at all. Judging by the short time I have had it , it is the best used car I have yet to see. The car was starting and running fine (no ticking sounds or noises) , even while the sparkplugs were still the originals. Even the air conditioning outclasses most others I have seen. It has not needed any service.
This car exceeds what I wanted in a car as a kid - classy styling - by adding aggressive handling. Boasting head-turning looks, it has no problem flying around corners near the speed limit with little assistance from the brakes. It's capable of stopping fast enough that I'm worried about air bags deploying. Sluggish out of early gears. Has no problem picking up speed at higher speeds. Mine was purchased used. After manufacturer PCM reprog for Tranny control error code, the system shifts gorgeously. Bad for the wallet as it coaxes me into driving 'a few extra miles'.
I found this car a pleasure to own. Although the 2005 is more desired I find my 2004 more than adaquate and I love the look. Not as Grandma as the Buick I replaced and there was nothing wrong with my buick except it was considered an old folks car. With this car I have both.
