You better have some serious, serious cash if you're going to lease a porsche (or something equivalent) for the remainder of your life @ little down and $1000-$1500/month if some of these figures are accurate. I say this because you mentioned in another post that you just graduated college a couple of years ago.
Unless of course you only plan to splurge on a leased Porsche for a few years and then suddenly you'll drop back down to earth by driving a car that's more commensurate to your income and wealth level.
Most Porsche leasers I know are quite poor or squarely middle class.
Edit: Alternatively, if you have wealthy parents who are paying for you then have at it
. No problem splurging as long as you or your family memers have the cash.
