This record's own overview states that Tradecraft Specialties lists RPO Z15 as the El Camino's Super Sport package throughout the 1978-1987 run, named "SS Sport Decor" for 1985, and describes it as up-level trim with SS badging and rally wheels rather than a distinct model line. This record's own dek identifies the car as the fifth-generation El Camino, with no production count from a verifiable source found for the SS package itself.1

This record's own key facts state that Choo Choo Customs of Chattanooga produced an El Camino SS conversion for GM from mid-1983 through the end of 1987 production, and that for 1985 a 4.3-liter fuel-injected V6, LB4 at 130 net horsepower, replaced the 3.8-liter V6 as the El Camino's standard engine, and that a four-speed overdrive automatic became newly available, both changes stated on the kit's own "What's New for '85" page. They add that the August 1984 price pages in the kit list the El Camino 1GW80 and the SS Sport Decor Z15 but print no prices at all, so no 1985 price from the kit itself appears in this record.1

This record's own production rows carry a single figure from a different source than the GM kit, 25,482 El Caminos built for 1985 across all trims, and the record's own note says plainly this total is not an SS count and that the article reporting it does not name its own source for the year. The production notes state that no Chevrolet production report was seen for this year, so an El Camino SS-specific count exists only as an unverified lead rather than a row in this record's own production table.2

This record's own prices section carries a single figure, $9,198, explicitly labeled as an El Camino SS base price reported by the same magazine article that supplies the production total, with the schedule date and basis both left unstated by that source. Its own unpublished leads section separately flags a Wikipedia claim of 21,816 total production with 1,198 SS units, sourced to a page that redirected to a paid-access gateway and so could not be verified, a third and lower total than either of the two production figures already documented elsewhere in this record.2

This record's own engines section documents the 130-horsepower LB4 262 V6 standard, with the record noting the same guide rating applied in California, and the 150-horsepower LG4 305 V8 optional, also carrying an unchanged California rating. Its transmissions section documents the MX1 three-speed automatic as standard and the MXO four-speed overdrive automatic as available in its place, giving buyers a choice between the two rather than a single mandatory transmission.

This record's own specifications section documents a 3,252-pound curb weight for the six-cylinder El Camino against 3,263 pounds with Z15 fitted, an 11-pound difference that follows directly from the two figures the record carries, a 117.1-inch wheelbase, and a 201.6-inch overall length. This record's own paint and interiors sections are both empty for 1985, and its performance, identification, and conflicts sections are likewise empty, a gap the record carries without substitution even where its engines and specifications sections are fully documented.
