Lowest optioned mopar you’ve seen
My RL21 Satellite had no carpet, no day/night mirror, and only body side molding (no drip rail, belt, or wheel moldings), no interior light group (no key light or glove box light). Base interior with no padding. Single note horn.
I believe the 318, disk brakes and wheel covers were all standard.
The only options I believe are AM radio (may have been std in 73), AC, and the BSM.
I've seen exactly ONE other car built the same way.
