Help

Here's the situation.
I know what vehicle I want to buy.
I know I can afford it.
My parents have to co-sign, and I don't want to make a major purchase without their blessing anyway.
They've agreed that I can make payments on something.
They want me to buy a fuel-efficent car.
They're probably thinking in the 8-9K range.

I want an '01-'03 Ford F150 King Ranch Edition truck.
Sure, it sounds like I'm being a moron, but I've done my research and know I can afford it. I've wanted one for years, so it's not like I'd be upset that I got it. It's a gorgeous truck that I'd love to own.

So how do I convince them to go along with it?
I need to compose a sensible argument.
Here's what I got so far:
A.) It'll help me establish good credit paying a regular payment for a long period of time.
I don't ever want a credit card. I'll put off getting one as long as humanly possible. But I need some way to get credit, and this could be a good opportunity. Not many other ways to establish credit.

B.) It's expensive, but I can afford it.
Right now I make around $900 a month. Bills are taken care of with student loans, so making a $350 payment would be a breeze. If it got tough, I still have poker. I could easily make the payment with poker earnings if needed.
C.) I'd be set for years.
This is a truck that adults would be happy to own, you can bet your ass that I'd be happy with it. I've wanted it for years, so I won't tire of it.

D.) I won't be immediately beset with maintenance troubles.
significantly less than 100K miles on it would beWe saw how long the 4Runner lasted, may it burn in hell. If I spend 8-9K, I feel like I'm driving a ticking timebomb. Buy a car just a few years old with awesome.
Z.) That leather is gorgeous.



Any more good reasons to give my parents? Let me know.
