The Pacer started out as an economy car, and eventually became a small luxury car.
The following information details some of the highlights.

The "X" Package: Available as the Pacer X from 1975 to 1978 in coupe form, this version was renamed Sport in 1978 and subsequently eliminated.
The trim package consisted of vinyl bucket seats, sports steering wheel and custom trim, as well as a floor-mounted gear shift and front sway bar.
The model received exterior chrome features, styled road wheels, Pacer X decals on the doors, and other package identification.

The "D/L" Package: A more upscale edition, the D/L was available for the entire run of the car and became the base model in 1978.
The package originally included "Navajo design" seating fabric and a woodgrain instrument panel as well as some interior features that were otherwise optional.
The exterior had additional chrome accents, different wheelcovers, and identification badging.

The "Limited": Available in 1979–1980, the Limited had leather seats, extra sound proofing, and deeper-pile carpet (18-oz.
vs. the standard 12-oz) as standard, plus amenities that were otherwise options, including: AM radio, power door locks, power windows, and tilt steering wheel.
The exterior had chrome accents, styled road wheels, and "Limited" badging.

The "Sundowner": Available through AMC dealers in California for 1975 only, the Sundowner was a basic $3,599 (suggested retail price) Pacer with options that listed for $300 included at no extra cost.
In addition to the mandatory California engine emissions controls and bumper guards, the package included "Basketry Weave" fabric upholstery with coordinated trim on the door panels, plus remote control exterior mirror, rear window washer and wiper, styled road wheels with white wall tires, and a roof rack.

The "Levi's" Package: Introduced for 1977 to capitalize on the popularity of the Levi's Gremlin and Hornet, the Levi's Pacer had blue denim-like upholstery and door-panel trim, with small Levi's tags on the front seats.
The copper buttons in AMC's other Levi's models were omitted, and a Levi's logo sticker was added to each front fender.
The version, which could be combined with the Pacer X package, did not sell in large numbers and it was dropped for the 1978 model year.

Carl Green Enterprises (CGE) Pacers: these cars, modified by automobile designer Carl Green, had 401 cu in (6.6 L) AMC V8 engines plus flares, air dams, and wings.
The CGE Pacers appeared in Hot Rod, Popular Hot Rodding, and Car & Driver magazines.
Green also built two Pacer pace cars for B.F. Goodrich to use in the International Motor Sports Association circuit, and provided body kits for Amos Johnson's Team Highball racecars.

Pacers without the optional vinyl roof trim could be finished in several unique two-tone paint combinations, with front and rear scuff molding extensions on the body sides.
The two-tone treatment was changed in 1977 to an "up and over the roof" accent paint scheme for the remainder of production.

For 1979–1980 a hood ornament and center chrome hood strip were added.
Moving toward more luxury features, power door locks became available in 1978 and in 1979 power windows joined the option list.
