AMG ML55. Was $140,000 in 2001, yours for $17,500. Spend another 5k on tinting, lift it so you can look down on others checking out your new enormous chrome wheels.
Spend $7,500 on return tickets to Laos (or any 3rd world country, but Laos would be my pick) and a year's food and accom.
You will then have approx 10k left over to hand out on a daily basis, in the form of food, at the orphanage of your choice. Perhaps even a daily english lesson too, to help them with job prospects.
I guarantee your outlook on life will change a thousand times more than the fleeting happiness any object will give you.
Couldn't afford it. But I did buy an electronics kit and am going to Kauai for a couple of weeks.
Oh silly me I forgot you were all butthurt after our last exchange.
Scratch what I said before, buy the Cayenne, it's the perfect car for you and you're the perfect driver for one 
Get a cheap piece of crap...
Travel with the left over cash
Update your leisure equipment
Enjoy life....
Or restore a car? Have seen a lot of nice restored Porsches lately. May still cost the same but price will be spread out meaning you can go all out and have some fun on the side with the rest of the car. Then when you flip the finger at the skyline behind you, you'd also feel a sense of achievement besides overtaking a kid in his car 
An older porsche would be a better investment and an older EVO a better performance option however neither would come with a warranty.
I would advise caution when using the term "investment" wrt any vehicle purchase.
(having taken a good number of $ haircuts over the years)
Best rule is to buy the least expensive car your ego can afford.
