If you go with Lambo, I highly suggest the Mercielago LP640 which is in my opinion the only Lambo worth owning.
If you opt for a Ferarri, I would highly suggest either the very rare and elite Enzo, or the F430.
But since you are asking this on yahoo, i suggest you keep your Civic or Cavalier or Neon or whatever peice that you actually do drive. haha
But think about this, this Reventon goes 0-60mph in 3.3 seconds and has a top speed of 211mph.
The 2008 Nissan GTR goes from 0-60mph in 3.5 seconds (almost the same) does the 1/4 mile in 11.7 seconds, can go over 200mph, has AWD, has a twin turbo setup, and costs only $70,000 US compared to 1 million Euro's for the Reventon.
Good Luck buddy
