I'm a Ford guy, but most of the time have had the oddball cars. I never owned a Mustang, but married a girl with a 69 351w coupe with a scoop. She still has it. I currently have a 70 429 4 speed Mercury Cyclone GT, a 64 Falcon Sprint convertible 4 speed with a 302 (1st year of the square body), a very rough 73 Bronco 351m, a 90 Bronco 351w, a 99 F250 crewcab V10, & a 40 Packard 110 sedan with a 243 6cyl.
Along the way I've owned a Tiger (Sunbeam body with a small block Ford V8, Maxwell Smart type car), a stock 68 302 4bbl Cougar, a 69 F250 360fe, a 56 Ford pickup 440 (Yeah, Dodge motor), & several other plain janes. It wasn't a muscle car, but I had a 58 Jaguar 3.4 litre sedan for awhile. I worked on it way more hours than I ever drove it.
