 I have had my 2003 C320 for about a 1 1/2 yrs and it was the worst purchase of my life. I bought the vehicle with 119k miles so I knew it would need some TLC but I never thought it would need as much as it has. 2 weeks after purchasing the alternator light came on. I have that replaced for about $400. Luckily I purchased an extended warranty and they covered half of the cost. I live in Indiana where the winters can be VERY cold and snowy. Rear wheel drive in the winter IS NOT FUN. During the summer it drove great but as soon as the temps reached below 50 the car started having issues starting. I would go out in the morning to start it and nothing. completely dead. I thought maybe it needed a new battery. So I spent $167 on a new battery. STILL HAD ISSUES. I am a single mother so I do not have time nor do I have the money to get this fixed. This car has made me late to work with it's starting issues multiple times. Thank God I will be trading this vehicle in soon. I also had other issues fixed that cost me around $900. This might be a flashy car, BUT NOT RELIABLE. I am done paying for premium gas and $60 oil changes. If you have to extra cash to throw around on this car to fix its issues everyone other week, then buy one! But I have had nothing but problems. The passenger seat also decided to stop working. There is just too much electric powered everything and the battery can not keep up or it is just made poorly. I will now be sticking with American made cars for the rest of my life. Thanks Mercedes-Benz for making a crap car and making me spend over $1000 just to get to point A to point B.
