Need Help, Might buy Honda Accord

Hi, I'm Lauren. I just turned 16 yesterday (although I have had my license for 8 months) and this weekend, I have the opportunity to buy a 1991 Honda Accord LX. The car has power everything, cruise, tilt wheel, air, AM/FM Radio, and cassette. It has 161,000 miles on it and has been well maintained by my grandparents. They want $3,000 for it. My question is, how long would this car last, is it a good car, and would it be worth it to buy it? Thanks for your help!
