Transportation Troubles

I need objective advice on what I should do in this situation.

I'm moving out on my own soon for the very first time. I have about $2000 saved-up, most of which will go into that launch. I'll need to arrange transportation for myself to work and so on. My first choice, based on lots of advice, was:

1) A motorscooter.

Pros: Insane gas mileage (~70 mpg); cheap ($2400 total, with affordable payments); cheap insurance; like a bicycle, which I'm used-to and comfortable with.
Cons: Nigh-useless in bad weather; not as safe as a car; can't haul things like furniture; in order to take a passenger, I have to get a motorcycle license (which is very easy from what I've heard).

My parents, naysayers that they are, hate the idea and prefer theirs:

2) They lend me their other car, which is currently sitting unused in the back yard.

Pros: Doesn't mind rain; safer; can haul things; can take several passengers.
Cons: Where do I start? It's a 1990 Chevy Blazer that rattles and bounces like it's about to spin apart. Even my parents have admitted that it's in dire need of massive mechanical work, which they claim they'll pay for. It doesn't actually run at the moment. It's filthy inside and out, and would require massive cleaning, spraying, scrubbing, bleaching, and vacuuming to not look and smell like a dumpster.

Bonus con: I don't have a driver's license. I have a permit and have to wait until the 24th to take a practical test. I have little (about three hours) driving experience, and actually have panic attacks when I think about driving and, once, when I actually was driving (which aren't helped at all by the fact that Dad gives me lessons only once every few weeks and laughs at me or yells at me whenever I make the slightest mistake). So even if I pass the practical, I doubt I can actually drive under normal conditions without going into a screaming panic behind the wheel. Remember, this is in contrast to the scooter, which I'm perfectly confident on.

Besides which, it'd still be their car. It'd still be their freaking control in my life. I want to be rid of them, and a huge part of that is having my own transportation.

There's an important nuance here, though: My parents don't have a lot of money to throw around. At least, they pretend not to (and then Dad goes out and tries to buy a new pool table). So I think they see this as their one way to help me out. Nevermind emotional support and encouragement; they want to palm off their lawn car and then be able to brag that they single-handedly orchestrated the entire moving-out. To deny them is to stab them in the ego, which is a pain to deal with. They're bitter enough about every single thing without having an excuse to spend the rest of their lives reminding me that I refused their car.

What the heck do I do?
