This is the third Mustang I have owned, and all I can say is that all three have been vey reliable, and the 2000 model has been the best I've owned. I'm well past the 100,000 mile mark and all I have had to do for repairs is replace the low pressure cutoff switch for the a/c (all of $30).
Performance, reliability, exterior design, and the Mach 460 stereo.
Better seats, and a much shorter throw shifter for the 5 speed. There is acreage between gears that robs the car of its full potential.
