What car deal is better for me?

I'm 20 years old and I don't really have any credit besides me paying my credit card bills. I belong to a credit union and since I don't have credit they let me qualify for a high school graduates program where I'm able to get a car for 12,000 and under. I found a car. It's 10,000. It's a 2008 honda accord with 100,000 miles. The credit union said I can get it with 600 down and 280 for 48 months. They also said they fix the car if some goes wrong with it. My second option is save 1000 for a down payment and go get me a newer car with a warranty. The payments may be higher but it depend on the car. Which deal is better?

Will the credit union guarantee that they will make the repairs if needed IN WRITING? It may be possible, but you would still need to have a mechanic do complete inspection of all systems prior to buying

Get a good beater that is not a flash car; those cost money and believe me I feel for the whole car thing and wasted my money when I was a youngin'. Use your money for something besides "Fast & Furious" wannabeing!

Hertz and other rental companies can sell you a car for that price range for a lot less miles and years.
