This thread is ridiculous. It's somebody with no genuine interest in cars, let alone high performance / supercars, asking a load of forum members how he should spend his money.
If you don't have enough of an interest to make your own informed decision about a car that you would like to own/run, then why would you bother outlaying all that money in the first place, especially in todays financial climate.
Just seems like you've got some money (If this is even real) and its burning a catastrophicly large hole in your pocket, and you don;t even have enough of an imagination to think what car you would like to buy.
Anyhow if it was me, I'd be spending around 30- 35k on an M3 CSL, and then putting the rest away. (Not in an Icelandic Bank)
