I bought my 2005 C230K at 67,000 mi for $13,000 three years ago and just turned 165,000 mi and am very pleased with it. I drive between Phoenix, Los Angeles and Las Vegas weekly and it has really never let me down. Plenty of kick from the supercharged 1.8L 4 cyl engine and the slap shift auto trans is great although it tends to over rev when putting it through extreme shifts at 70mph+.
I've had this car for about 3 mo's and bought it used with 78k and so far it's been a decent car. My gripe is mainly the lil buggy issues. 1. Driver side front parking lamp went out, now it's working again. 2. Instrument cluster stopped working however the center digital center gauge is working fine and the dash lights still work. In other words, all the needles are at 0. It's an excellend drive and it's pretty quiet on the road/freeway but Mercedes is suppose to be a well made automobile, but with little annoying things like this coming up it could potentially make the driver not want to purchase this brand of car again. Ps: This car has automatic trans.
I've had the car for about 4 months, and it's a great ride. Acceleration from a stop could be a little quicker, but once you get up to speed, this car rides nice. The 4Matic works great in the snow, and heavy rain. The car feels extremely solid for a smaller luxury car, and it handles very nicely. The interior design for 2005 makes a big difference, and looks much better than Audi, or BMW.

This is the best car I have ever owned, it rides so smooth and accelerates really good for a 4 cylinder thanks to the supercharger, and it will brake one a dime. And the fuel efficiency is even better I average 30 to 35 mpg on highway and about 20 to 25 in city. And there is plenty of space in the car and trunk. The things that I wish were different on my car is the front brakes and I wish that the tires wouldn't ware out so fast, after about 20,000 miles the front tires were bald and they were new when I bought them. Other then that I will always want to have a mercedes because of this car.
