I bought my '92 Grand Prix SE as my first car, I purchased it for $500. After putting about another $400 into it, it still needs some work done to it, but I absolutely love it. It's a great first car for anyone.
The way it handles.
The comfort of the seats.
Where the door handles are located.
The way GM has it all set up underneath the hood and just the make up of the car is a little stupid, but otherwise there isn't much I could really suggest for improvement.
