Earlier quoted context omitted.
The Vyron isn't a performance car. You can easily build an Ultima GTR for less than $100,000 with well over 600 HP. People often mistake expensive with fast, when expensive really means safe, luxurious, flashy and then fast. Ellison's roadster is not safe, or luxurious, but it is flashy and fast.

When you say "Vyron", I can only assume that you're talking about the Veyron , which decidedly is a performance car: BHP: > 1000 bhp 0 - 60: 253 mph Braking: 249 mph to 0 in Not a performance car, my ass. http://en.wikipedia.org/wiki/Bugatti_Veyron
Veyron:
P/W ratio: .24
Price: $1,400,000
Quarter mile: 10.2
Ariel Atom:
P/W ratio: .3
Price: $65,000
Quarter mile: 10.4
Ultima GTR:
P/W ratio: .333
Price: ~ $100,000
Quarter mile: 9.9
So the Veyron is only $90,000 (6.4%) worth of performance and $1,310,000 (93.6%) of something else. It is an overpriced luxury car that is fast. An Ariel Atom or an Ultima GTR is a 100% performance (aka "race") car.
