The fixed-head coupé and 2+2 GT derivatives of the AC Ace — the Bristol-engined Aceca leads the market.
The Aceca (1954–1963) is the fixed-head coupé derivative of the AC Ace, sharing the Ace's tubular chassis with heavier-gauge main rails, an extra crossmember and rubber differential mountings; the body uses wood-framed doors and tailgate rather than the Ace's tube construction.
Three engine options were offered: the Aceca with the 1,991 cc AC SOHC inline-six (85–105 bhp across production); the Aceca-Bristol with Bristol's 1,971 cc inline-six based on the pre-war BMW M328 (105 bhp B-type or 125 bhp D-type); and the Aceca 2.6, with the 2.6-litre Ford Zephyr Ruddspeed unit from 1961. Total production was 328: 151 AC-engined, 169 Aceca-Bristol and 8 Ford 2.6. The Aceca-Bristol outsold the AC-engined car and added approximately $1,000 to the $5,400 US base price. Front disc brakes were standardised from 1957; overdrive was available from 1956.
The Greyhound (1959–1963) is the 2+2 grand touring derivative, announced at the October 1959 Motor Show on a lengthened 100-inch wheelbase (versus the Aceca's 90-inch). Two-door four-seat aluminium body; same engine options — AC 2.0L (75 hp), Bristol 2.0L (125 hp) and 2.2L (105 hp), Ford 2.6L (170 hp); the majority were Bristol-engined. 83 were built. All variants were capable of exceeding 100 mph.
The Bristol-engined Aceca leads the market; the Greyhound commands a rarity premium within a thin market.

Authenticate stamped chassis and engine numbers against factory or club records. For the Aceca specifically, verify engine type against chassis records (AC SOHC, Bristol B/D-type or Ford Zephyr Ruddspeed) and the presence of front disc brakes and overdrive where period-correct. For the Greyhound, confirm the 100-inch wheelbase and engine option against club records.
Confirm body originality, panel identity and restoration standard against a marque specialist.
Confirm continuous service history and any rebuild history for the engine, transmission and driveline against a marque specialist.
Restoration standard, originality of body and driveline, and any documented ownership record are the main value drivers.
