What is a fair price for a silver/black 98 M3 coupe, 58,000 miles, HK, sport, paint looks absolutely flawless, new rotors and pads and tires (RE71/RE730) all around? Asking price is over $28k. Is this too high? Just right? I know this is some mileage, but the car is very clean -- hard call for me. Thanks in advance.
