Past appreciation is not a guarantee of future value. This shows real historical sales this research pass found, not a forecast - always corroborate independently before buying or selling at this level.

Reference Specs

Road-homologation "Sport Quattro" (214 built, 1984 only): 2.1L turbo inline-five, ~306hp, 320mm shorter wheelbase than the standard Quattro
Works "S1"/"S1 E2" (only 20 built): Up to ~500hp+, the ultimate S1 E2 evolution reportedly ~550hp, sub-1,100kg

History

Built to homologate a shorter, more powerful Group B evolution after Peugeot's 205 T16 and Lancia's 037 raised the bar - driven by Röhrl, Blomqvist, Mikkola and Mouton, before Group B was banned by the FIA after 1986 following fatal accidents.

💡 Serious collector buyers weigh documentation and originality above all else - matching engine/chassis numbers, a continuous service history, and factory paperwork. AutoLytiQs provides real reference specs for this nameplate; verifying a SPECIFIC car's authenticity against them (or via a marque specialist) is a real, separate step worth taking before paying a premium price.

⚠️ Pitfalls To Watch For

Replica/tribute builds exist internationally: Some built on Audi S2 running gear with Sport Quattro-look bodywork - always verify the chassis number against the ableitet.no registry or FIA historic database before treating any car as genuine.
The 214-off road "Sport Quattro" and the 20-off works "S1"/"S1 E2" are frequently confused in marketing: Match against chassis number, not seller wording - the value difference between the two is enormous.
No South African sale exists or was found: This car was never sold in SA - both real dated sales shown above are US auctions, converted for scale. Real international benchmarks range even wider, from real, documented auction results of £1.8m to over €2m (RM Sotheby's, Bonhams, Artcurial), not shown as dataPoints here since they lack the same specific per-lot detail as the two used above.

An Enthusiast Investor's Take

Beyond the Numbers

The Sport Quattro/S1 carries something almost none of the South African-market cars on this list can claim: direct, undisputed motorsport pedigree at the absolute top level - Group B rallying - with a story that's been told and retold in international media for 40 years, and that kind of narrative weight is exactly what separates a car that merely appreciates from one that becomes a genuine blue-chip. The honest risk is entirely about verification and originality, more than for almost anything else here: because the mythology is so strong and the real cars so few, this is precisely the kind of nameplate where replica or heavily "improved" examples circulate at real-car prices - an enthusiast investor's actual expertise needs to be in Group B Audi history specifically, not just Quattros generally, before this is a serious consideration at this price level.

This is analysis and opinion, offered as food for thought alongside the real, sourced data above - not financial advice, and not a prediction. Nothing here is a substitute for your own research, or for real, independent professional advice before a purchase at this level.

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 Audi Sport Quattro / S1 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.
