Hi Everyone! I'm really interested in buying a 2006 or 2007 C Class but the common theme seems to be the balance shaft. I have 2 cars in mind and I was wondering if anyone can help me decide if its a good deal.

First car is a 2006 C280 with 110,000 miles on the odometer. The exterior is in great condition but the front seats are cracking slightly and they want $8000 from a dealer. VIN#WDBRF92H36F787575

The second car is a 2007 C280 with 41,000 miles on the odometer. This car is in great shape but they want $13,000 for it. VIN#WDBRF92H87F853958

Any help is appreciated. Thank you so much ahead of time.
