If you are looking for million dollars and above, It is Bugatti Veyron.
of course the Porche, Ferrari and many others are in between the price range.
If 300,000 dollars is too much for you for a car, the lowest priced high performance car (production) that can probably have the guts to face Veyron is the Nissan GTR.
The Nissan GTR is the lowest priced performance car it is a little over 100,000 dollars for the 2013 model. The 0-60 for Veyron is pretty much confirmed at 2.4 sec and the GTR is 2.6 to 2.7.
Some pretty fast cars that look odd to me at least.
1. Ariel Atom V8 --- This is the fastest 2.3 0-60 , but it does not look safe for a daily drive.
2. Caparo T1
3. Ultima GTR
If you are not a big fan of Nissan GodZilla, here are some cars that can be pretty fast..
1. Henessy Venom GT
2. Saleen S7
3. SSC Ultimate Aero Twin Turbo
4. Ascari A10
Those are the possible fastest cars I read about. It all depends on the driver.
For the highest top speed
1. Buggati Veyron Super Sport can go up to 268 Miles per hour.
