Hi everyone, I am interested in purchasing a Mercedes Benz C250 AMG. At the moment I own a C230 Sport. I've serviced my car and it runs good. I was wondering if I would be upgrading or downgrading if I was to purchase this c250 AMG. The AMG has 62K miles and cosmetic wise looks nice. They are selling it at 7.8k. I've talked him down 7.3k already. I test drive it this Sunday. Am I buying a terd or is this a good move? Any help is appreciated as this would be my 2nd car purchased.
