I saw the yellow one (non roadster) at Pebble Beach last year and had the 'pleasure' of speaking with John Hennessey. If you've ever been to Pebble Beach, you'll know that you'll see/rub elbows with all manner of 'car guys' - from uber billionaire collectors to enthusiasts to car company executives. In just spending a few days there, we met and chatted with/took photos with tons of people including: Schwartzenegger, Dan Neil (Car Show), Barry Mequiar, Wayne Carini from Chasing Classic Cars, Dany Bahar (yep), Stephan Winkelman (CEO of Lambo), Cate Blanchett (yep, that Cate Blanchett), the Austrian dude who played the bag guy in Inglorious Basterds and many others. Most were very nice (for example, Barry Meguiar was a phenomenally nice man).
Of note, the Venom was in the lobby of the Portola Hotel. I go to look at it and find myself next to Michael Anthony of Van Halen - have a bunch of pics. We started talking cars and John Hennessey and crew walk up. After a small chat, Michael Anthony's lady friend, who used my iPhone to take the pics, turns and comments about what an a$$hole Hennessy and his peeps were!
On to the car. Sorry, I don't see it. It's cheating. This is Pagani, Koeningsegg, Bugatti money. Those cars are their OWN (regardless of the say AMG engine in the Pagani). Taking a Lotus Exige and an LS9 engine and doing all sorts of voodoo, just doesn't justify the price tag.
Also, what about resale? Even rocker guys sell cars. For example, I know a guy that has Steven Tyler's old Panoz AIV Roadster. Hell, I own two snare drums that I bought of of Tim 'Herb' Alexander from Primus! Rock guys sell off stuff!
What will the resale value of this car be? And yes, I'm sure they care. Paganis and Veyrons still command a king's ransom. I think this would depreciate rapidly. There's no provenance, no panache, no uniqueness is motoring history - it's just a frankenstein'd car
