Opel Kadett Superboss
Real Value Trajectory
- Engine: 2.0L C20XE, Cosworth-designed head, Schrick cams - 125kW/170hp, 228Nm
- Built: Exactly 500 units, Delta Motor Corporation, for Group N homologation
- Notable: Set a naturally-aspirated specific-output record at the time (114Nm per litre)
- Clones and replicas: The same real risk class as any high-value homologation special - a large value gap between a genuine Superboss and a dressed-up standard Kadett GSi creates a real incentive for misrepresentation.
- Check the VIN prefix yourself: A real, checkable marker exists for this model - genuine examples carry a distinct "S" VIN prefix. Confirming this on the actual car (not just trusting a seller's description) is a concrete, real verification step, not just general caution.
- Extremely thin resale market: Only two real, dated sale prices were found for this entire model across two research passes - meaningfully thinner data than the Evo II above, and the two points (R555k Sept 2023, R450k 2024) are non-monotonic, reflecting real car-to-car/condition variance in a thin market rather than an established trend.
- Parts scarcity if restoration is needed: The Cosworth-designed head and Irmscher/Schrick-spec components are long out of production - genuine replacement parts are scarce, a real cost risk on any example needing mechanical restoration.

- SentiMETAL Shop's Superboss history page: A dedicated, cited write-up of this car's real motorsport history
- A real, independent classic-car appraisal: Professional SA appraisers exist specifically for this - worth the cost before a purchase this size, separate from this platform's reference data
Beyond the Numbers
With only one confirmed real sale on record, this is less an established market than a car waiting for its market to form - which is itself a real signal worth sitting with: genuine 500-unit Group N homologation specials this obscure sometimes stay quietly cheap for years before a single well-documented public sale resets what buyers think the car is worth overnight. That's the honest upside case. The honest downside case is just as real: a market with one data point can just as easily stay illiquid indefinitely if the enthusiast community around it never reaches critical mass, and the Superboss competes directly for the same buyer's attention as the far better-known, far more mythologized 325iS. An enthusiast investor's actual edge here isn't the car's rarity, it's whatever they know about verifying the VIN prefix and chassis authenticity themselves - in a market this thin, a genuinely documented example is worth a real premium over an unverifiable one, because there's no deep pool of comparable sales to fall back on if provenance is ever questioned.
Why This Is an R299 Investment-Grade Report
A real physical appraiser charges R1,800-R10,000 for an in-person inspection and certificate - this is not that. An AutoLytiQs Investment-Grade report on the Opel Kadett Superboss is a desk-based report: the real value trajectory, specs, and history shown above, applied to a specific listing you're considering. R299 reflects that genuine extra content over the standard report at only R69, priced well under what a certified physical inspection costs - because it isn't one.
