Model years shown among the diecast and kit listings include 1957, 1967, 1979 and 1986.
The vehicle models are offered mainly in 1:24 scale, with some items also available in 1:25 scale.
Diecast models are primarily metal with some plastic parts; the plastic model kit is made of plastic.
Most model items are packaged as a single unit (package quantity 1); at least one diecast listing shows a package quantity of 2.
Assembled model lengths fall in about a 7–8 inch range, with listed dimensions around 7, 7.25, 7.5 and up to 8 inches.
Suggested ages vary by item: some toy/diecast models list "3 Years and Up", one lists "8 Years and Up", a kit lists "14 Years and Up", and the books list "22 Years and Up".
Common features include real rubber tires, steerable wheels, true‑to‑scale detail, official licensing, and functional openings (hoods/doors — and in some cases trunk and detailed interior/engine compartments).
The books are richly illustrated histories and references covering engineering, design, milestone cars and every production year; page counts shown include 240, 256 and 320 pages across the titles.
The plastic model kit is a multi‑part assembly (listed as 105+ parts) at skill level 2 and requires paint and glue; a paint guide and decals are included and the finished model assembles to about 7 inches.
