The Hennessy is crazy money, period.
Hennessey takes a used Elise / Exige ($35k?), sells-off the hardware thats not needed ($10k?), uses the Lotus' V.I.N. (zero expense for homologation) & re-builds using body / rear frame / suspension from a UK company based in Silverstone and their own engine tune-up. All the other parts like brakes, gearbox, gear linkage, engine etc are from typical OE suppliers like Brembo, Ricardo, GM....
Without a wild engine tune, Venom should be in the $100k - $150k zone.... similar to Noble's old price position. Above $200k... there's sooo many great supercars, that have been properly developed from the ground up with bespoke engineering. The 'Lotus Hennessey' is just out classed.
I always find it funny that when interviewed, John Hennessy gives no credit to Lotus regards the base car being an Elise / Exige. Beyond the big stuff like the chassis tub, doors, glass, interior etc all being Lotus, all the smaller items that really make a road car, a road car, are Lotus too : HVAC, seals, lights, bulkheads... even the alarm & central locking is Lotus.
I don't accept in any way, that the Venom is like a 'modern Cobra'... without Lotus, there would be no Venom as it is today... its would more like a FF GTM kit car.
Lotus developed the Elise GT1 back in the mid 90's to take over from the ageing Esprit. It took Hennessy 2 decades to copy the idea.
