Thing is, when one needs a car, craigslist is right there.
When one wants a car but doesn't need it, it is so simple.
"I have X dollars here in my fist, and they are yours if the car is mine."
No haggling necessary. Don't tell me what car it is, because I already know.
The problem is with Joe Q Public - he wants a car and tries to talk himself into thinking he needs it. And here's Uncle Sam with the $4500 in hand...
If our friend DavidV here needed a family hauler, he'd gone out and bought a 5-year old Odissey minivan from the 'list. But being a self-proclaimed automotive expert, he needs to test new wheels every once in a while and report his findings to the public... Mind it, I don't even question his choice of junking the Disco (it's a disaster like a typical surfer dude special) - just lame attempts to rationalize it.
