They both got to be named POS, until I realized the phone charger I just got was blowing the 15 amp accessory fuse after I replaced the stereo. Fortunately I figured it out soon enough to only replace the bad stereo that was put in the blue car 12 years ago. It wasn't working for crap before. Now it works great and picks up channels a lot better, even with the original speakers, now 22 years old. Probably the first blown fuse in either car.

That Mustang reminds me of a 67 390 GT I once owned. You could just drive that thing around in top gear and never down shift unless you stopped. My 59 Vette could be shifted 1-4 and back without using the clutch, I think the 390 GT would do the same. Ever drive a 39 Ford truck with the crash box, straight cut gears.
