This guide covers the full 275 family (GTB 2-cam short- and long-nose, GTS Pininfarina spider, GTB/4 four-cam, GTB/4*S NART Spider, the 3 GTB Speciale/GTB/C Series I prototypes and the 12 GTB/C of 1966). The auction results table carries the original GTB-guide entries unchanged, with each existing result labelled [AGGREGATOR] to reflect that it was sourced from a compiled results document and cross-referenced against auction-house records rather than independently fetched during this range-expansion review. No new results were added for the newly-covered GTS, GTB/C or NART Spider variants: no [PRIMARY] fetch was performed in this review, and rather than publish [UNVERIFIED] entries none are listed. NART Spider public-auction context is discussed in the market commentary only.
2026 Monaco/Indianapolis batch sourcing (original note, retained): entries dated 2026-04-25 (RM Sotheby's Monaco) and 2026-05-08 through 2026-05-16 (Mecum Indianapolis) were sourced from a compiled results document, cross-referenced against auction-house records, mapped to the correct model/generation, and inserted with prices and lot numbers preserved verbatim. Independently fetch-and-quote verified from those two sales (elsewhere in this dataset): Ferrari 599 GTO (Mecum Lot S199), Lamborghini Miura SV (Mecum Lot S148), Porsche 959 Komfort (Mecum Lot S133), Singer 911 Reimagined (Mecum Lot F166), Mercedes-Benz 190E 2.5-16 Evolution II (RM Monaco Lot 152), and Acura NSX (Mecum Lot S185). Other 2026 Monaco/Indy entries in this table are not independently fetch-verified.
