Fint, actually I agree with you. I doubt any of the three years of the Bullitt Mustang will become a sought after collector's car. Some on the Bullitt board get a bit upset when I say that. However, Bullitt Mustangs do seem to depreciate less than many others. Definitely less depreciation than a similarly priced "Luxury GT" Mustang of the same year.
The resale on mine could plummet to zero, and I still won't have depreciated as much as a new 911 does the second it leaves the dealership. I paid exactly $30,075 for mine new, licensed and out the door. That was in April of '09. In the 10 years since, it's been a zero hassles car. Battery, wipers, and tires replacements..that's it.
29,300 miles.
That said, no, not the fun driver the old 911S was. Mustang heavier, so not as nimble..but Mustang is faster than the old S. Handles okay for street driving, doing everything well but nothing in a spectacular manner.
I will confess to thinking about the latest '19 Bullitt with 480 horsepower. Espencially now that dealers are starting to dump the old "additional dealer markup" thing. Mechanically, it's pretty cool. The power, the 6 speed manual, the Torsen rear end, magnetic shocks, Brembo brakes, etc. Sort of a sleeper 350GT. But, it's heavily gadgeted up with electronics. The young guys seem to love all that stuff...I don't.
So, considering my age & the real world driving I do? Well, the '09 Bullitt Mustang could well be my final car. In the current Mustang world, it's old, slow, and obsolete. Kinda fits me...
