Alex,
Any chance you can have one of your parents add it to one of their policies? That would probably be about the only way you'll get away without taking a major beating.
Even then, I would imagine that with a 15 year-old listed as a primary driver, you're gonna git hit-up for alot more than what you want to pay.
I don't know what insurance runs in Alabama, but I can tell you $1,200/year doesn't really sound that bad, considering you're a new driver, single, and a male to boot.
My first car, a 1955 Chevy was $1,500/year just for liability and that was back in the late 70's. In the early 80's I lost my license for 6-months. When I got it back, the truck I had at the time was costing me about that every 6-months.
Sorry I don't have any better ideas but... As far as insurance goes, you can only hope that you become 25 and married real quickly.
You might give some of those insurance broker types, (like Progressive) a shot. Good Luck.
