Four rounds down, and you're still here for more — respect. This week we're pulling questions straight from two of the wildest cars headed to the block: a Superformance MKI GT40 wearing Gulf Racing heritage livery, and a track-only 2022 Porsche 911 GT2 RS Clubsport 25 built with Manthey-Racing. Then we threw in a handful of classic car and auction trivia to see how deep your knowledge really goes.

Score
QUESTION 1
A Its top speed of 140 mph, rounded to 40B The 40 units built for the 1966 racing seasonC Its overall height of 40 inchesD Ford's internal "Group 40" prototype program
Correct!
Not quite — the answer is: its overall height of 40 inches. "GT" for Grand Touring, "40" for the roofline that barely cleared a Le Mans starting grid photographer's knees.
QUESTION 2
A Big-block 427 side-oiler V8sB Small-block Ford V8s (289/302/351W)C A GM LS-series crate V8D A flat-plane-crank Coyote V8
Correct!
Not quite — the answer is: small-block Ford V8s. It's the same recipe the original street-friendly Mk I road cars used, and the continuation carries a GT40/P chassis number that's eligible for the official GT40 Registry.
QUESTION 3
A Set the fastest qualifying lap in 1965B Won the 24 Hours outright in both 1968 and 1969C Debuted the first rear wing seen at Le MansD Were disqualified for a fuel-tank rule violation
Correct!
Not quite — the answer is: won the 24 Hours outright in both 1968 and 1969, run by John Wyer Automotive Engineering under sponsorship from Gulf Oil.
QUESTION 4
A Manthey-Racing's 25th anniversaryB 25 years since the 911 GT2 nameplate debutedC A 2.5-second 0-60 timeD 25 years since Porsche's first Nürburgring 24 win
Correct!
Not quite — the answer is: Manthey-Racing's 25th anniversary. Olaf Manthey founded the team in 1996, and Porsche has owned 51% of it since 2013.
QUESTION 5
A 10B 30C 50D 77
Correct!
Not quite — the answer is 30, a track-only run split globally, with just 6 originally allocated to U.S. customers. (77 was the production cap on the road-going 935 tribute — nice try if you picked that one.)
QUESTION 6
A FerrariB AudiC ToyotaD Porsche
Correct!
Not quite — the answer is Porsche, with 19 overall victories and counting.
QUESTION 7
A The odometer and service records line up exactlyB The engine and other major components are original to that specific carC The VIN matches the number on the key fobD Two owners paid the exact same price for the car
Correct!
Not quite — the answer is: the engine (and often transmission and other major components) are original to that specific car, not swapped in later.
QUESTION 8
A Its fin-shaped taillightsB A wing-shaped hood ornamentC Doors that swing open upwardD An early rear spoiler design
Correct!
Not quite — the answer is: doors that swing open upward, a solution born from the car's tube-frame chassis rather than pure style.
QUESTION 9
A LotusB AC CarsC Austin-HealeyD MG
Correct!
Not quite — the answer is AC Cars, whose Ace roadster became the basis for the Cobra once Shelby got a V8 under the hood.
QUESTION 10
A An extra fee added on top of the winning bid, paid by the buyerB A discount offered to returning biddersC Insurance included automatically in the sale priceD A tax rebate for first-time buyers
Correct!
Not quite — the answer is: an extra fee added on top of the winning bid, paid by the buyer. It's also where BIDR's low rate stands out from the rest of the industry.
