Im looking at purchasing 2003 s55 45k miles or a 2004 s 500 27k miles. Is there a maintenance problem with the amg car as i reach higher mileage. 5k difference in price. any input would be great. Is insurance considerably higher.. My love has always been the s 55..I did own a new 2002 s 500 and did enjoy it just didnt like the depreciation of purchasing new.. If there are any issues with these models please let me know..can purchase newer if needed.. these just wont need the banker!! Thanks for your time..
