Advice on extending the driveway for parking

[jcd]

With two teenagers driving, our driveway is like a used car lot.

I want to extend the driveway to add parking. My guess is 2 cars worth, however big that is. I currently have an asphalt driveway.

Any ideas on the cost or an inexpensive alternative.

PS, I'm someone who will undertake a totally ridiculous DIY effort in an effort to save $25.

TIA
