i currently own a 1995 C220 with 120,000 miles i love it but am interested in purchasing a newer mercedes. I have two options, a 1998 C230 kompressor with 140,000 miles for $7,000 (silver) or a 1997 mercedes E420 with sport pakage and 85,000 miles, (silver) I know the history of the E420 as it is owned by a family friend. I probably can get it for around 10,000 dollars but i am worried about the cost of owning it. i know replacement tires alone cost about 200 dollars each. Or should I look for a used Bmw 325i 1999-2001. I like the way they drive i just feel more loyalty to mercedes benz.
