I am looking at a 2004 loaner C240 4matic. The Car has 7500 local miles. Absolutely Perfect Condition. Original delivery and owned by local dealership. The Car listed for 36,700. Went into service one year ago. I have negotiated down to 28,500 dollars. Since it is a 2004, it includes the balance of the 4/50 factory. It also includes the scheduled maintenance. Thoughts? Is it a good deal? Should have them change the oil before delivery if I buy it? The computer says it is not due for another 5,000 miles or so. I would appreciate advice to a newbie. Is this a good car to buy? How is quality on the 04 model year?
