Loaded , good candition, has ABS issue

I am the original owner. This 300C is loaded with every option available including the Boston Acoustics 6 disc stereo, navigation unit, heated leather seats, sunroof, adjustable pedals, rosewood steering wheel etc. It was our daily driver up till a year and a half ago. An ABS brake issue developed and by the time it was diagnosed we had bought another car. Most cars will allow you to drive with the ABS system light one but the 300C will automatically go into limp mode until it is fixed. It partially locks out the transmission stopping it shifting. It will only go into first, reverse, neutral and park. This still allows it to drive however top speed is only about 15 mph. The dealership told me it was either the ABS module or it was the rear drive axle "tone rings". They create a magnetic field that the ABS sensor detects. It is located at the end of the axle and sits in the hub.I have an aftermarket axle for each side but have not installed them. I changed the ABS module and ABS box but it will need either the original module reinstalled (just the module but with the replacement box) or the computer re flashed at the dealership as the ECM realizes that it is not the original module. I still have the original module and box and it is included. The car will need to be towed but can easily drive on and off a trailer. The exterior is in good condition overall and has an almost new set of Pirelli P6 tires. The interior is in very good condition and only has one slight wear area on the driver's seat bolster. The driver's fender has minor rust bubbles above the wheel opening (see picture). The passenger hood hinge need replacing (stiff).
Buy it, fix it, and drive it, or buy it and part it out, you will make a ton. I don't have the time.The car is located about 20 miles east of Detroit, Michigan just over the Canadian border. The car can easily be imported to the USA as it meets all standards.
