Equipment
Only in England could they construct such a fantasy. Shortened PII chassis and running gear (PI gearbox). WWI Packard built V 12 27 litre Liberty airplane engine with 420hp and 1,300lb ft (!) at 1650rpm. Open rubout style bodywork. Recently completed.
Market commentary
Impossible to value such a special, but the quality of the components and workmanship assure that it was a labor of love, not profit. Think about driving a PII with this power, on hard, skinny tires. Think about updating your will.
