Why shouldn't I buy one of these?

late to the discussion, but anyways....
Don't buy your dream car right off the bat. It'll leave you with no hopes for later life.

Also, don't speculate too much before you know how much you'll make... in real money terms. It can be quite daunting with all your expenses. You just have to see it. No amount of predicting will do it.
