^^^Cantflip: So your saying the value of the '75 Imperials should be less because of the brakes?
In my observation, yes... an informed purchaser (IDK how rare those are), would be more likely to seek out an nice 76-77 New Yorker.
Edit: the rear discs make them worth more to a few of us... but most of the uninformed will hate the car as soon as they find out how easy parts are to come by.
1974- Unique grilles and small rear window(also used on Salon package in 78)... also the last of the slightly bigger, early T&T steering wheel.
1974-75- Unique rear side marker light bases, using the 1971 lens. Unique and long obsolete rear disc brakes (standard feature, no drums used to my knowledge)... I know of only 2 sets of rotors widely advertised on the internet over the last few years... both are used and expensive. I have a box of cores for the parking brake shoes... I might look into having them relined someday. The dash pad is also unique, but interchangeable with the other Formal dash pads.
1975-77 had the same or similar trim overall... including grilles. AFAIK the options available on NYB's were pretty close to the same as the Imperial standard/option list.
1976-77 Other than the lean burn debate, these cars had the majority of the best parts or at least the easiest to find parts.
1978- New grille, smooth bumper fillers and taillight lenses with a center rib are the only exterior cues I can think of. These cars had a radical redesign of components (to reduce weight?). There are a few well known 78 only issues, but the number of parts that are slightly different is amazing (for a one year car). The wiper bushing failure is reason enough for some folks to avoid the cars. They are still much easier than rear discs to devise a work around... rear discs only real work around is elimination and downgrade to a rear drum setup
.
All Formals have good brakes, when working... so not the end of the world.
