I am going to look at a black 03 mach I with 489 actual miles on it. this car is at a dealership and they are holding it for me until i look at it. I am not new to the mustang world, just Mach I's. they are asking 21,100.00 for it. I would like to know if this is a fair price and what i should look for in the car when i go. it is suppose to be in showroom condition. any help would be appreciated.
